## About Us

SensAI was built with a simple belief: everyone deserves a personal trainer who understands their body, adapts to their life, and helps them reach their goals. We combine the reasoning power of large language models with personal health data from Apple HealthKit to create coaching that's genuinely personal — not templates with your name on them.

## What We Do (Features)

* **Smart Planning**
  AI generates training programs from scratch based on your goals, equipment, schedule, and constraints. Programs regenerate every week based on what you actually did and how your body recovered. Not templates — built for you.

* **Workout Tracker**
  Guided set-by-set tracking with exercise illustrations, highlighted muscle groups, rest timers with Lock Screen Live Activities, and real-time heart rate zone breakdown. Works offline and syncs when connected.

* **AI Coach**
  A conversational coach powered by LLMs that uses your history, injuries, and preferences. Send photos for form feedback, meal analysis, or gym equipment identification. Modify workouts mid-session with natural language. The AI remembers important context across sessions.

* **Recovery & Readiness**
  Apple HealthKit integration uses permitted HRV, resting heart rate, sleep, workout, and activity context from Apple Watch and other devices that write to Apple Health. This data feeds directly into programming decisions — the right intensity on the right day.

* **Progress Tracking**
  Personal records, workout streaks, milestone tracking, and performance trends with baseline comparisons.

## How SensAI Is Different

SensAI is powered by large language models — the same class of AI behind ChatGPT and Claude. This is not rule-based logic or template matching. The AI reasons about your training the way a knowledgeable coach would, combining your personal health context with evidence-based exercise science. Your wearable data provides the "what's happening with your body" picture; the LLM provides the intelligence to act on it.

## Privacy

SensAI reads selected Apple Health data on-device and syncs the summaries and metrics needed for coaching, workout history, recovery context, and progress views. No data is sold to third parties.

## Topics We Cover

* Strength, hypertrophy, and flexibility programming
* Recovery science and HRV-based training
* Zone 2 training and cardiovascular fitness
* Wearable data interpretation and application
* AI and technology in fitness
* Injury prevention and working around constraints

## Target Audience

* People who take training seriously but don't have access to a dedicated human coach.
* Busy professionals who need programs that adapt when life gets in the way.
* Wearable device owners who want their health data to actually inform their training.
* Anyone from beginner to advanced looking for evidence-based, personalized programming.
