What you get
AI Coach
Reads your full training history via Apple Health. Recommendations reflect what you really did across every fitness app, not just what you logged here.
On-Device AI
Apple Intelligence is free. One-time unlock adds Qwen 2.5, Phi-3.5, and Llama 3.2 fully offline — no API keys, no rate limits, no cloud at all.
Animated Demos
Curated GIF library for the lifts you actually train. Anatomical muscle diagrams as a fallback. Bring your own video for niche moves and form references.
Strength Programming
Pre-built and AI-generated programs with progressive overload baked in. Fractional weight precision — 12.5 lb micro-loads and 0.25 kg jumps both work.
Polished Rest Timer
Strong haptic and a can't-miss banner when rest ends. Overage counter so you can take an extra minute without the timer disappearing on you.
Apple Health Sync
Bidirectional. Workouts feed your Activity rings and the Workouts app. Body weight reads back automatically for any bodyweight lift.
Privacy by default
Workout data lives on your device and your private iCloud account. AI requests run on-device when you choose Apple Intelligence or the on-device model. Cloud providers (OpenAI, Claude, custom endpoints) are bring-your-own-key and only see what you ask them. No analytics, no tracking, no third-party SDKs.
