Fitbod vs Strong vs Hevy vs SensAI: $24 to $96 a Year

Here’s the 30-second verdict:

Strong is the fastest pure logger — you bring the program, it stays out of the way ($29.99/yr, $99.99 lifetime).
Hevy is the best value, the only real free tier, and the strongest community ($23.99/yr).
Fitbod has the best automated programming if you want the app to plan every session ($95.99/yr).
SensAI is the only one that coaches off your wearable recovery data ($69.99/yr).

The mistake is picking by feature count. Pick by training style instead — the wrong match is what gets an app deleted by February.

What Changed in 2026

Strong added a $19.99 six-month plan, slotting between its $4.99 monthly and $29.99 annual options.
Everything else held steady — we re-verified all four apps’ pricing in July 2026 and found no changes since our last update. In a market that hiked prices for two straight years, stability is itself information.
Hevy Trainer, Hevy’s AI workout generator, remains included with Pro at no extra charge.

Pick by Training Style, Not Feature List

Would you hire a coach based on how many certifications they list, or based on whether their style fits how you actually train? Apps work the same way. A feature you’ll never use is worth exactly nothing — the question is which app’s core loop matches yours.

Strong: You Already Have a Program

Strong is a precision instrument for one job: logging sets faster than anything else on the market. If your program comes from a coach, a spreadsheet, or a decade of your own experience, Strong records it without ever suggesting you do something different.

That restraint is the product. No algorithm second-guesses your programming, CSV export keeps your data portable, and the interface is optimized for the ten seconds between sets. The $99.99 lifetime purchase is increasingly rare in a subscription-saturated market.

The trade-off is total silence: no workout generation, no recovery awareness, no guidance of any kind. Strong assumes you know what you’re doing — and if you do, that’s precisely what you want.

Full head-to-head: Hevy vs Strong in 2026.

Hevy: Best Value, Real Free Tier, Community

Hevy is the only app here with a genuinely usable free tier, and at $23.99/yr, Pro is the cheapest paid plan of the four. You also get the strongest social layer: a feed of workouts from people you follow, PR celebrations, and the quiet accountability of lifting in public.

That social layer isn’t fluff. A 2024 meta-analysis of 36 randomized trials found gamified fitness apps produced a measurable step-count increase over non-gamified ones — modest, but real.¹

Hevy Trainer adds AI-generated workouts at no extra cost, though it’s lighter-touch than Fitbod’s engine or SensAI’s coaching.

Fitbod: The App Does the Programming

Fitbod answers the question that stops most beginners cold: “What do I actually do at the gym today?” Tell it your equipment and experience, and its algorithm generates each session — rotating muscle groups, tracking its internal model of fatigue, and pulling from a library of over 1,000 exercises with video demos.

For guided, hands-off programming, it’s the most mature engine in this comparison. The catch is the price ($95.99/yr, the most expensive here) and the ceiling: Fitbod’s fatigue model is built from your logged workouts, not from your body. It doesn’t see your sleep, HRV, or resting heart rate, so a brutal night’s sleep and a perfect one produce the same recommendation.

SensAI: Coaching That Reads Your Recovery

SensAI is the only app in this lineup that uses your wearable’s recovery data — HRV, sleep quality and duration, resting heart rate — to decide what today’s training should look like. Apple Watch connects directly; Garmin, Oura, and WHOOP flow in through HealthKit.

The coach itself is an LLM with memory: it remembers your injuries and preferences across sessions, and you can modify a workout mid-session in plain language — “make it shorter,” “my shoulder’s acting up” — and it rebuilds on the spot.

Honest framing on the science: HRV-guided training shows small group-level advantages over fixed plans, but its clearest benefit is fewer people who get worse — reduced downside risk, not magic.² For anyone who struggles to know when to push and when to back off, that’s the point.

The column that matters is not “works with your watch” but “uses your data to coach you.” Fitbod, Strong, and Hevy log workouts from your wrist; none of them changes your programming because of what your wearable measured overnight.

App	Offline support
Strong	Fully functional, syncs when reconnected
Hevy	Fully functional, syncs when reconnected
Fitbod	Logs workouts offline after session starts
SensAI	Offline-first — full workout tracking without internet; AI coaching features need connectivity

2026 Pricing: $24 to $96 a Year

Hevy costs $2.99/month or $23.99/year for Pro; the free tier is genuinely usable with limits, and a $74.99 lifetime option exists.

App	Monthly	Annual	6-month / Lifetime	Free tier / Trial
Fitbod	$15.99	$95.99	—	7-day trial, no free tier
Strong	$4.99	$29.99	$19.99 6-mo, $99.99 lifetime	Minimal
Hevy	$2.99	$23.99	$74.99 lifetime	Free tier with limits (Trainer included with Pro)
SensAI	$6.99	$69.99	—	7-day trial

For context: a human personal trainer runs $200–400 per month. Even the priciest app here costs less per year than two coaching sessions — so the real question isn’t Fitbod’s $96 versus Hevy’s $24, but whether the extra features change how you train. SensAI’s $69.99/yr works out to about $5.83/month for coaching that adapts to your recovery daily.

Does the Technology Actually Matter? What the Research Says

The dirty secret of fitness apps isn’t bad software. It’s abandonment.

A 2024 scoping review covering 18 studies and over 525,000 users found a median of 70% abandon lifestyle apps within the first 100 days.³ A 2026 study of one fitness app’s user base measured a 69% drop-off in training activity by the end of the first month — though paying subscribers stuck around nearly twice as long as free users.⁴ The counter-signal: a 2025 pilot of an AI-biomarker wellness app held weekly engagement at 43.5% a month in, roughly triple industry norms.⁵ Whatever app you pick, the feature that matters most is the one that keeps you opening it in March.

Social and gamified features measurably help. The 36-trial meta-analysis found gamified apps added roughly 489 steps per day over non-gamified equivalents,¹ and the Columbia Moves cluster trial found teams with gamification kept up their self-monitoring habits better months after the intervention ended.⁶

What about AI coaching and recovery-guided training? The evidence is real but bounded. In a Johns Hopkins randomized trial led by Ahmed Hassoon, MD MPH, an AI voice coach drove an increase of roughly 3,600 steps per day over control — a striking effect, measured in cancer survivors rather than lifters, so translate with care.⁷ A scoping review of AI-driven activity apps found positive effects on behavior, with certainty ranging from moderate to very low.⁸ And on the recovery side, Agustín Manresa-Rocamora’s group at Universidad Miguel Hernández found HRV-guided training’s standout result was the responder rate: in the reviewed trials, half of runners on fixed plans lost aerobic capacity, versus about one in nine trained by HRV.² A separate systematic review in the Journal of Science and Medicine in Sport reached a similar conclusion for wearable-measured HRV in endurance training.⁹

Marco Altini, PhD — founder of HRV4Training and author of more than 50 papers on the subject — frames HRV the way the research supports: a day-to-day readiness signal that only means something against your own baseline, telling you when to ease off, not how fit you are.

Be clear about the limitation: these are activity and endurance studies, not studies of lifting apps. No RCT has pitted Fitbod against SensAI. But personalization that responds to your actual physiology is where exercise science is heading¹⁰ — and that is the bet SensAI makes: reading the recovery signals your wearable already collects and adjusting your training before you dig a hole.

Quick Head-to-Head Answers

Fitbod vs Hevy: which is better?

Fitbod if you want the app to program every workout for you; Hevy if you want value, community, and control. Fitbod plans each session automatically but costs four times as much; Hevy gives you templates, a social feed, and light AI generation for $23.99/yr with a real free tier. Beginners who want zero decisions lean Fitbod; everyone else keeps more money and more say with Hevy. Full comparison: Hevy vs Fitbod.

Hevy vs Strong: which should you pick?

They’re the two best pure loggers, and Hevy wins on value while Strong wins on speed. Hevy is cheaper ($23.99 vs $29.99/yr), has a usable free tier, a community feed, and Wear OS support. Strong’s logging flow is slightly faster and its $99.99 lifetime option rewards commitment. If social features do nothing for you, Strong; if you’d rather pay less and see friends’ PRs, Hevy. Full comparison: Hevy vs Strong.

Fitbod vs Strong: programming or logging?

This is the cleanest split in the roundup: Fitbod decides your workouts, Strong records them. If you have a program you trust, Fitbod’s $95.99/yr buys you an algorithm you’ll be fighting; Strong’s $29.99 buys a faster notebook. If you’d otherwise wander the gym improvising, Fitbod’s structure is worth the premium.

FAQ

How much does Hevy cost?

Hevy Pro costs $2.99/month, $23.99/year, or $74.99 for lifetime access, and includes Hevy Trainer AI workouts. The free tier works indefinitely with limits on routines and analytics.

Is there a free version of these apps?

Only Hevy has a genuinely usable free tier. Fitbod and SensAI are trial-based (7 days each, then paid), and Strong’s free version is minimal enough that practical use means paying. If “free forever” is the requirement, Hevy is the answer.

Can I switch apps without losing my workout history?

Mostly, yes. Strong offers straightforward CSV export; Fitbod and Hevy support export, though some export features sit behind their paid tiers. SensAI pulls your historical health and activity data in through HealthKit, so your training context follows you.

What’s the best workout tracking app in 2026?

There is no single best — there’s a best match for your training style. Self-programmers should use Strong or Hevy; people who want the app to plan everything should use Fitbod; people with a wearable who want training that adapts to their recovery should use SensAI.

The Bottom Line

If you have a program and want speed → Strong.
If you want maximum value, community, or a real free tier → Hevy.
If you want the app to do all the programming → Fitbod.
If you want coaching that responds to your body’s recovery signals → SensAI.

One honest note: when people quit a workout app, the usual failure mode is a mismatch between the app and how they train — not bad software. All four of these are good at what they’re built for.

If what you’re missing is a coach that knows you slept badly before you tell it, SensAI has a 7-day free trial — connect your Apple Watch, Garmin, Oura, or WHOOP and see what recovery-aware training feels like.
