Lyfta Review 2026: Price, Free vs Premium, Is It Worth It?

Lyfta is a gym workout tracker from a small Norwegian company. It calls itself “free, simple, and ad-free,” has 4.8 stars from 7,177 ratings on the US App Store, and lists more than 5,000 exercises with HD video guides.¹

The short answer on price: the Lyfta app is free, and Lyfta Premium costs $9.99 a month, $49 a year or $149 for life in Lyfta’s US web checkout.² The App Store lists ten unlabeled prices instead, which is why some new users say the “free” app asked them for $60 a year.¹³

Every price, limit and feature below was checked on 30 October 2026 against Lyfta’s App Store and Google Play listings, its own website and web checkout, statements from Lyfta staff, and PubMed. SensAI makes a competing app, so we show where SensAI loses as well.

Is Lyfta worth it in 2026?

Yes, for most lifters, because the free version is unusually complete: unlimited logging, unlimited routines and the full 5,000+ exercise video library. Premium adds analytics, all-time charts, programs and strength rankings. Lyfta’s web checkout lists it at $9.99 a month, $49 a year or $149 for life.⁴²¹

US App Store listings and Lyfta’s web checkout, checked 30 October 2026.

Lyfta’s strengths are the free plan, the library and the reach: it runs on iPhone, Android, Apple Watch, Wear OS and the web, and imports history from six other apps.¹⁰ Its weak spots are confusing pricing, a paywall screen at the end of sign-up, thin progression guidance, and integrations that promise more than users report.³¹¹¹²

How much does the Lyfta app cost? Lyfta pricing in 2026

Lyfta itself is free. Lyfta Premium costs $9.99 a month, $49 a year (with a 14-day free trial) or $149 lifetime in Lyfta’s US web checkout. The App Store lists ten unlabeled “Lyfta Premium” prices from $5.99 to $79.99, and Google Play lists $4.99–$79.99 per item.²¹¹³

Where you buy	Monthly	Yearly	Lifetime
Lyfta web checkout (US)	$9.99	$49, after a 14-day free trial	$149
US App Store	Not labeled	About $60, per users	Not labeled
Google Play (US)	$4.99–$79.99 per item13	Not labeled by plan	Not labeled by plan

Web prices from the pricing data Lyfta’s checkout at my.lyfta.app loads for the US, 30 October 2026; the checkout itself needs a login.² App Store and Google Play prices from their US listings.¹¹³ The iPhone yearly figure comes from user reviews, not from Lyfta.³

Lyfta does not publish prices on its own website. Its subscription page says “Lyfta Premium pricing varies by country and is shown in the App Store and Google Play before you subscribe,” and that monthly, annual and lifetime options “may be available depending on your region.”⁴

Which Lyfta price is monthly, yearly and lifetime?

Only the web checkout names its plans: Monthly $9.99, Yearly $49, Lifetime $149. On the App Store, all ten items are called “Lyfta Premium”: $59.99 twice, $49.99 twice, $29.99, $79.99, $5.99, $12.99, $11.49 and $17.99. Users report “$60/year” after the trial, which matches $59.99.²¹³

So the iPhone yearly plan is most likely $59.99. One new user described the last sign-up screen this way: “it says it’s free for 2 weeks and then $60/year.”³ Lyfta has not said which App Store item is the monthly plan or the lifetime plan, and there is no $149 item in the App Store list, so iPhone lifetime pricing differs from the web.¹²

The other App Store prices are probably regional, older or promotional versions of the same plans. That is a guess, so treat the checkout screen on your own phone as the real price.

Is Lyfta cheaper on the web than in the App Store?

Yes, for the yearly plan. Lyfta’s US web checkout charges $49 a year, against the roughly $60 a year iPhone users report. Paying monthly on the web costs $119.88 a year, so the $49 annual plan saves 59%. Web prices are billed by Lyfta, not Apple, so Apple’s refund route does not apply.²³¹⁴

Here’s what this means for you. If you know you will stay for a year, the web checkout is the cheapest regular price we found. If you want Apple to handle billing, cancellation and refunds, pay in the App Store and accept the higher price.

Is there a Lyfta lifetime subscription?

Yes. Lyfta calls it “Lyfta for Life”: Premium “without a recurring subscription when lifetime access is available.” The US web checkout lists it at $149. At the web yearly price, it pays for itself after just over three years.⁴²

Plan (US web)	1 year	2 years	3 years	4 years
Monthly, $9.99	$119.88	$239.76	$359.64	$479.52
Yearly, $49	$49	$98	$147	$196
Lifetime, $149	$149	$149	$149	$149

Lifetime only makes sense if you are confident you will still log with Lyfta in 2029. Compare Hevy, whose lifetime plan is $74.99, and Strong, whose PRO Forever is listed at $99.99 and $79.99.⁵⁶

Does Lyfta have Black Friday deals or promo codes?

Yes, but don’t plan on last year’s price. A Lyfta staff member wrote in September 2026 that “last year’s Black Friday deal was exceptionally cheap, and we don’t expect it to be that low again.” Referral codes can unlock rewards such as a 30-day Premium trial for both people.¹⁵¹⁶

Lyfta also says offers “can vary by region,” and partner promo codes from creators “typically offer discounts on Lyfta Premium.”¹⁵¹⁶

Is Lyfta free, or does it cost money? What the free version includes

Yes. Lyfta says it “is free to use: you can log workouts, build routines, and browse 5,000+ exercises with HD video guides without paying.” The free plan has unlimited workout logging, unlimited routines, the full video library and basic progress tracking, with no ads shown.⁴¹

That makes Lyfta’s free plan more generous than its two best-known rivals. Hevy’s free plan allows up to four saved routines, seven custom exercises and three months of history. Strong’s free plan saves unlimited workouts but only three custom routines.⁹⁶

The free plan also gained a rest timer “for everyone” in September 2026, with a countdown timer and a stopwatch, and Lyfta’s staff confirmed that “unlimited workout routines remain free.”¹¹

One limit is unclear. Lyfta’s subscription page lists custom exercise creation as a Premium feature, while a September 2026 staff update said “unlimited custom exercises are coming in the next iOS update.” Check before you rely on many custom lifts on the free plan.⁴¹¹

Lyfta free vs Premium: what does Premium unlock?

Premium adds analysis rather than logging. You get workout analysis and recaps, all-time progress charts, strength standards and rankings against lifters of similar age and bodyweight, premium programs, a plate calculator, automatic warm-up sets and body measurement tracking. Logging, routines and the library stay free.⁴¹¹

Feature	Lyfta free	Lyfta Premium
Workout logging, sets, reps, weight, RPE, notes	Yes1	Yes
Routines	Unlimited4	Unlimited
5,000+ exercise video library	Yes4	Yes
Rest timer	Yes, since September 202611	Yes
Workout analysis and weekly/monthly recaps	No	Yes4
All-time and year-long progress charts	No	Yes4
Strength standards and rankings	No	Yes4
Premium programs	No	Yes4
Plate calculator and automatic warm-up sets	No	Yes411
Body measurements and muscle radar	No	Yes4
Custom exercises	Limited; sources conflict	Yes411

Lyfta’s own summary is fair: “The free version covers everything you need to track your training.”⁴ Premium is for people who want the numbers interpreted.

Is Lyfta Premium worth paying for?

Pay for Premium if you use the charts every week, want to see how your lifts rank, or want ready-made programs inside the app. Skip it if you mainly log and repeat your own routine; the free plan already does that well. At $49 a year on the web, it costs about twice as much as Hevy Pro’s $23.99.⁴²⁵

Some users discover the line late. One App Store reviewer could not save their own progress photo, suspected it was a Premium feature, and wrote: “It doesn’t say anywhere that that is a premium feature.”³ Start the 14-day trial, use the charts for two weeks, and keep Premium only if you opened them.

How long is the Lyfta free trial, and how do you cancel?

The Lyfta free trial lasts 14 days on eligible plans; on the web it comes with the yearly plan. App Store subscriptions renew automatically unless you turn off auto-renew at least 24 hours before the period ends. Cancel where you paid: Apple, Google Play or your Lyfta account.¹²⁴

• App Store: in iPhone Settings, tap your name, then Subscriptions, then Lyfta, then Cancel Subscription. Apple says that if there is no Cancel button, “the subscription is already canceled.”¹⁷
• Google Play: follow Google’s guide to cancelling a subscription on Google Play.
• Web: Lyfta says “you can manage your Premium plan from your Lyfta account or through the platform where you subscribed.”⁴

Lyfta’s App Store listing says the trial is for “Lyfta Pro,” while the in-app item and the website say “Lyfta Premium.” It is the same upgrade.¹⁴

Can you get a refund from Lyfta?

For App Store purchases, request refunds from Apple at reportaproblem.apple.com; Apple says to expect an update within 24 to 48 hours and that eligibility varies by country. On Google Play, the developer handles most refunds. Lyfta’s terms publish no web refund policy, so contact support@lyfta.app.^14181910

Set a calendar reminder for day 12 of the trial. The most common one-star review of Lyfta is about the subscription screen, not the app itself.³

Does Lyfta have AI? The workout generator and ChatGPT connector

Lyfta has two AI features, and neither is an adaptive coach. A free AI workout generator on its website builds a routine from a prompt, and a read-only connector lets ChatGPT, Claude and similar assistants read your completed workouts. Lyfta does not automatically suggest weight or rep increases.²⁰²¹¹¹

The generator lives at lyfta.app/workout-generator. You type a request such as “Can you create a full body strength workout?” and get a routine, without an account or a subscription.²⁰

The connector is the more unusual feature. Lyfta describes it as “a read-only training connector”: “ChatGPT, Claude, Cursor, and similar agents call the API with an OAuth token for that Lyfta user. They never get write access,” and they can read up to 90 days of your training.²¹ It is a clever idea for lifters who already use an AI assistant, but the assistant cannot change your plan inside Lyfta.

What Lyfta lacks is built-in progression. In September 2026 a user asked for “an algorithm that suggests automatic progressive overload within the selected program,” and Lyfta’s team replied: “Suggestions on when to increase weights or reps within your program could totally be useful! We’ll keep it in mind!”¹¹ For now, Lyfta shows your previous numbers and leaves the decision to you. If you want software to make that call, read our guide to AI progressive overload.

Does Lyfta work with Apple Watch, Garmin, Fitbit and Strava?

Lyfta works with Apple Watch and Wear OS for live logging, connects to Apple Health and Health Connect, and shares completed workouts to Strava. It lists Garmin and Fitbit as integrations, but Lyfta staff say it doesn’t send workouts to Garmin Connect and that Fitbit Air does not sync directly.^113101222

Connection	What Lyfta says	What users and staff report
Apple Watch	“Apple Watch support for live workout tracking”; watchOS 10.6 or later1	One October 2026 review says rest-timer alerts don’t vibrate on the watch3
Wear OS	Log workouts from the watch, with Tiles for quick starts13	Not reviewed here
Apple Health	“Sync with Apple Health and Strava”1	Not reviewed here
Health Connect	Listed integration10	Not reviewed here
Strava	“Connect Lyfta to Strava to automatically share completed workouts”13	Not reviewed here
Garmin	Listed integration10	Staff: “Lyfta doesn’t send workouts to Garmin Connect today”12
Fitbit	Listed integration10	Staff: “Fitbit Air data won’t currently sync directly with Lyfta”22
Google Fit	“Lyfta does not integrate with Google Fit”10	—
Imports	Hevy, Strong, Fitbod, Boostcamp, JEFIT and FitNotes10	Google Play names Hevy and Strong CSV files13
Export	“CSV export is available”10	—

The import list is a real advantage if you are leaving another tracker. Lyfta’s own Hevy comparison warns that “some custom exercises may need manual mapping.”²³

For Garmin owners, the safer route is Apple Health or Health Connect: Lyfta’s strength sessions and your watch’s runs can meet there. If you want to know what else reaches Strava, see what syncs with Strava.

What does the research say about tracking your lifts?

Logging works. A meta-analysis of 138 studies found that monitoring progress improves goal attainment, especially when the progress is physically recorded. Fitness apps raise activity modestly, but the effect fades and many users drop out. A tracker helps most when you log every session and act on the numbers.^24252627

Does logging workouts help you progress?

Yes, modestly. In Harkin and colleagues’ meta-analysis of 138 studies and 19,951 people, monitoring goal progress improved goal attainment (d = 0.40), with larger effects “when the information was physically recorded.” Logging every set in an app does exactly that.²⁴

App studies point the same way, with caveats. Laranjo and colleagues pooled 28 trials (7,454 adults) and found a small-to-moderate effect of apps and trackers on physical activity, about 1,850 extra steps a day; interventions with personalisation worked better.²⁵ Romeo and colleagues found that programs shorter than three months were more effective than apps evaluated for longer.²⁸

The fade is real. Across 117 trials of mobile health programs, the few with long-term follow-up found effects lasted, but “the effect size decreases over time.”²⁶ And in app-based programs for chronic disease, the pooled dropout rate was 43%.²⁷ A free app with no limits removes one reason to quit, but it can’t make you open it.

What should you look at in your Lyfta stats?

Weekly sets per muscle. Brad Schoenfeld and colleagues found “a graded dose-response relationship whereby increases in RT volume produce greater gains in muscle hypertrophy,” and a 2026 meta-regression of 67 studies confirmed that gains rise with volume, with diminishing returns. Lyfta Premium’s muscle split analysis shows that distribution.²⁹³⁰⁴

Schoenfeld is a professor at Lehman College in New York who has published over 350 peer-reviewed articles.³¹ In his 2017 meta-analysis, each extra weekly set was associated with an extra 0.37% gain in muscle size.²⁹ The 2026 analysis by Pelland and colleagues found that counting indirect work as a fraction of a set fit the data best, and that strength shows “considerably more pronounced” diminishing returns than size.³⁰

You don’t need Premium for this: you can count sets by hand from the free log. Our guide to training volume per muscle covers the ranges.

Should you log RPE and RIR?

Yes, if you can rate honestly. Trained lifters predicted reps in reserve on the bench press with high accuracy (mean absolute error 0.65 reps), and effort-based loading worked as well as percentage loading for strength. Lyfta lets you log RPE and RIR on any set, free.^32333413

Eric Helms, a researcher at the Sport Performance Research Institute New Zealand at Auckland University of Technology, led a 2018 trial comparing the two approaches. His team concluded: “Both loading-types are effective. However, RPE-based loading may provide a small 1RM strength advantage in a majority of individuals.”³³ A 2022 meta-analysis found that autoregulated loading, adjusted by effort or bar speed, and standard percentage loading produced similar strength gains.³⁴

Logging effort also tells you whether you need to train to failure. A 2023 meta-analysis co-authored by Helms found only a “trivial advantage” for failure training on muscle growth, and “no evidence” that it is superior.³⁵ Lyfta’s “failure sets” tag is useful for spotting how often you go there. See our guide to RPE and RIR for how to rate a set.

Can you progress without adding weight?

Yes. In an 8-week trial of 43 trained lifters, adding reps worked as well as adding load: “Both progressions of repetitions and load appear to be viable strategies for enhancing muscular adaptations.” Lyfta’s “Previous” values make either approach easy to track, even without automatic suggestions.³⁶¹¹

Do strength standards and rankings matter?

They are a useful motivator, and strength itself matters for health. A meta-analysis of about 1.9 million people linked higher grip strength to a 31% lower risk of death, and muscle-strengthening activity is linked to 10–17% lower all-cause mortality. Lyfta’s rankings compare you with lifters of similar age and bodyweight.³⁷³⁸⁴

Lyfta describes its strength levels as percentile bands: “beginner ~5%, intermediate ~50%, advanced ~84%, elite ~95%.”³⁹ Lyfta calls them “statistical estimates, not coaching prescriptions,” built from “statistical strength models built from lifter data,” so use them to track your own trend rather than to judge yourself.⁴⁰ For population tables, see strength standards by age and bodyweight.

Can you learn lifts from video alone?

Video helps knowledge more than results. In a trial of 79 students, an online weight-training course taught with video demonstrations improved knowledge but not strength, and the authors pointed to “lack of motivation, low accountability.” Lyfta’s 5,000+ videos are a reference, not a coach.⁴¹¹

The study is from 2008, so treat it as a caution rather than a verdict on modern apps.⁴¹

What do Lyfta users complain about?

The most common complaint is the sign-up paywall: five of the 50 most recent US App Store reviews say the “free” app asked them to subscribe. Others report lost or “missed” workouts, repetitive muscle labels in the library, Apple Watch alert bugs and integrations that do less than listed.³¹²²²

• The “free” paywall. “Not “free” as advertised”: “As soon as you create a login and answer questions about your goals, you’re required to start a subscription.”³ Other reviewers say the opposite once past it: “they don’t push the premium purchase on you like other gym apps… a lot of stuff is free but the stats are premium.”³
• Lost data. “Completed workout yesterday, got final screen with total weight, etc. Today it shows as missed.”³
• The library. One three-star reviewer wrote that it “uses the same muscles names for every specific workout.”³
• Watch alerts. “Rest timer notifications are not vibrating neither on apple watch, just the sound.”³
• Progression. A four-star review asks Lyfta to “give you suggested increases.”³

These are individual reviews, not a survey, and the overall rating is still 4.8 on iPhone and 4.75 on Android.¹¹³

Is Lyfta safe? What data does it collect?

Lyfta is a registered Norwegian company and shows no ads, but its App Store privacy label says it collects identifiers and usage data “used to track you,” including for third-party advertising. Its Google Play label says no data is shared with third parties. Apple notes that labels are not verified.⁴²¹¹³

The likely explanation is ad attribution for Lyfta’s own marketing, not ads inside the app, but the label does not say. If tracking matters to you, turn off “Allow Apps to Request to Track” in iPhone settings. Lyfta’s user-count claims are also inconsistent: “over 7 million” on the App Store, “over 5 million” on Google Play, and “1M+” Android installs.¹¹³

Who makes Lyfta?

Lindberg Development AS, a Norwegian company founded in Kristiansand in April 2021, with seven employees. Its founder and CEO, Kolbjørn Lindberg, earned a PhD at the University of Agder in 2023 with a thesis on force-velocity profiling for athletes.⁴²⁴³⁴⁴

Lyfta says it was “started by two brothers: a scientist and an engineer, both lifters,” and that “every recommendation in Lyfta is grounded in training research, not fitness trends.”¹⁰⁴⁴ It is not related to lyfta.com, an education platform with the same name.¹⁰

Lyfta vs Hevy, Strong and Fitbod: which is better?

Lyfta beats Hevy and Strong on the free plan, the exercise library and imports. Hevy and Strong are cheaper to upgrade ($23.99 and $29.99 a year) and have far more App Store ratings. Fitbod is a planner, not a log: it writes your workouts for $95.99 a year. Of the three trackers with a free plan, Lyfta’s is the most generous.⁴⁵⁶⁷

If you want…	Pick	Why
The most generous free tracker	Lyfta	Unlimited routines and the full video library, free4

Lyfta vs Hevy: Lyfta’s free plan has no routine cap, while Hevy’s stops at four. Hevy has about 14 times as many App Store ratings and a cheaper Pro plan.⁴⁹⁵¹ For the full head-to-head, including Liftoff, read Liftoff vs Lyfta vs Hevy and our Hevy review.

Lyfta vs Strong: Strong caps free routines at three and costs $29.99 a year for PRO, but its Apple Watch app can log without an iPhone. See our Strong app review.⁶

Lyfta vs Fitbod: Fitbod decides your exercises, sets and weights; Lyfta records what you decide. Fitbod is a subscription after its free trial. See our Fitbod review.⁷

Where does SensAI fit?

SensAI is a conversational AI coach for iPhone and Apple Watch. You tell Coach what you need, it writes and adjusts your plan, and it reads Apple Health, so sleep and overnight heart rate shape how hard it asks you to push. It costs $6.99 a month or $69.99 a year after a 7-day free trial.⁸⁴⁵

The difference from Lyfta is who decides. Lyfta records your plan and shows your previous numbers; SensAI’s listing says “Smart Modify can shorten your workout, change its intensity, or shift its focus. Just type what you need.”⁸ Per SensAI’s Help Center, “Sleep and overnight heart rate from your device shape how hard Coach asks you to push on a given day.”⁴⁵

There are limits on that data. SensAI reads Apple Health only, so your device’s own app has to write there first. Apple Watch is the only device that shares HRV that way, and vendor scores such as Garmin’s Body Battery, WHOOP’s Recovery and Oura’s Readiness never cross.⁴⁵ To see what your device shares, read how to connect a wearable to SensAI through Apple Health.

Where Lyfta beats SensAI:

• Price. Lyfta’s free plan never expires; SensAI has a 7-day trial, then $69.99 a year.⁴⁸
• Platforms. Lyfta runs on Android, Wear OS, the web and iOS 16; SensAI is iPhone and Apple Watch only and needs iOS 26.¹⁰¹⁸
• Library and imports. 5,000+ exercises against SensAI’s 500+, and imports from six apps.¹⁸¹⁰
• Track record. 7,177 US ratings against SensAI’s 39.¹⁸

Where SensAI is different: a coach that writes the next session, a plan you can change by typing, and recovery data that changes the day’s workout.⁸⁴⁵ No trial has tested SensAI’s coaching either, so judge both on how they fit your week.

Who should use Lyfta, and when is a Lyfta alternative better?

Use Lyfta if you write your own training and want a free, ad-free log with a huge video library on any platform. Pick something else if you want the cheapest upgrade (Hevy), a phone-free watch app (Strong), or a coach that writes and adjusts your plan (Fitbod or SensAI).⁴⁵⁶⁷⁸

Frequently asked questions

Is Lyfta free?

Yes. Logging, unlimited routines and the 5,000+ exercise video library are free with no ads. Premium is optional and adds analytics, all-time charts, programs and strength rankings. A trial screen at sign-up confuses some users; you can use the free plan without subscribing.⁴¹³

How much does Lyfta Premium cost?

In Lyfta’s US web checkout, $9.99 a month, $49 a year or $149 lifetime. The App Store lists ten unlabeled “Lyfta Premium” prices from $5.99 to $79.99, and iPhone users report about $60 a year. Prices vary by country and platform.²¹³

How much is Lyfta per month?

$9.99 a month in the US web checkout. On the yearly plan, $49 works out to about $4.08 a month. Lyfta does not label which App Store price is monthly.²¹

Does Lyfta have a lifetime subscription?

Yes, “Lyfta for Life.” It costs $149 in the US web checkout and pays for itself after about three years of the $49 yearly plan. The App Store list has no $149 item.⁴²¹

How long is the Lyfta free trial?

14 days on eligible plans; on the web it comes with the yearly plan. Referral codes can give a 30-day trial. Cancel at least 24 hours before it ends to avoid being charged.⁴²¹⁶¹

Is Lyfta better than Hevy?

For free users, yes: Lyfta has unlimited free routines and a 5,000+ video library, while Hevy’s free plan caps routines at four. Hevy is better if you’ll pay, at $23.99 a year, and want a large social feed.⁴⁹⁵²³

Does Lyfta work with Garmin?

Not directly. Lyfta lists Garmin as an integration, but its staff say you can’t log sets from a Garmin watch into Lyfta and that Lyfta “doesn’t send workouts to Garmin Connect today.” Use Apple Health or Health Connect as the bridge.¹⁰¹²

Does Lyfta have an AI coach?

No. Lyfta has a free AI workout generator on its website and a read-only connector for ChatGPT and Claude, but no in-app coach that adjusts your weights or reps.²⁰²¹¹¹

Can I import my Hevy or Strong data into Lyfta?

Yes. Lyfta imports workout history from Hevy, Strong, Fitbod, Boostcamp, JEFIT and FitNotes, and some custom exercises may need manual matching.¹⁰²³

The bottom line

Lyfta is one of the best free workout trackers in 2026: unlimited logging and routines, 5,000+ exercise videos and apps on every major platform. Premium is worth $49 a year on the web only if you use its charts and rankings. Its costs are murky App Store pricing, a sign-up paywall and no progression guidance.⁴²³¹¹

If you want a log that stays free and imports your history, start with Lyfta and ignore the trial screen. If you want the cheapest upgrade, Hevy is half the price. If you want a coach to decide what you lift next, Lyfta isn’t trying to be that app.
