A deterministic engine plans your training, adapts to your readiness from Apple Health, and shows you exactly why.

Anneal runs the same deterministic, published rules on every workout, including the ones you build yourself. Tap any set and see exactly why it moved.
Every morning, Anneal reads your HRV, sleep, and resting heart rate from Apple Health, then adjusts today’s training to match how recovered you really are. It only ever scales back, never past your plan.
Anneal’s streak is weekly, not daily, so one bad day never resets you to zero. Want a bigger goal? Trials are fixed challenges, up to 75 days, that forgive the same way.
Tell Anneal what equipment you have, and it shows exactly which muscles and movements you can fully train today. If something’s capped, it even suggests the single best thing to buy next.

Comparison reflects public pricing and app reviews as of August 2026. Full Anneal vs Fitbod comparison. Fitbod and Hevy are trademarks of their respective owners.
Every new install gets three weeks of full Pro access, completely free, no card required. After that, the core logger stays free forever, and Pro is there if you want more. Export is always free, and canceling takes two taps.
There’s nothing to sign up for, and your training data lives on your iPhone unless you turn on optional sync. Even then, nothing is ever sold, shared, or used to track you.
Now, on the App Store for iPhone (iOS 17+), plus Apple Watch.
Yes. Anneal imports CSV exports from Strong, Hevy and Fitbod (Settings → Data → Import CSV), and exports your own history as CSV any time, free. Your e1RM curve picks up where you left off.
No. The Watch adds rest-timer haptics and wrist logging; everything still works phone-only.
iPhone first. Excellent beats mediocre on two platforms. We’ll revisit if earned.
No. Anneal trains healthy lifters, caps load jumps conservatively, only ever reducing on low readiness. Pain or injury? See a professional.
Free logger forever. No account required. Every set explained.
