Stronger every week,
by design.
Anneal plans every set and raises it when you’ve earned it. It knows which muscles are still sore, adapts to how you slept, and shows you exactly why each weight moved.

An engine, not vibes.
Anneal runs the same deterministic, published rules on your program, generated sessions, and the lifts you add yourself. Finish a workout and next time is already planned. Rate a set and the rest of that lift adjusts. Tap any set and see exactly why it moved.
Double progression: last session you hit the top of your rep range at 85 lb, so the bar goes up one step, to plates you can actually build.
It knows what’s still sore.
Every set you log heats up the muscles it worked on Anneal’s recovery map, and they cool as you recover. After a session, a five-second check-in shares its guess, like quads at 21% recovered. Tap Feels right, More sore, or Less sore, and it tunes how fast each of your muscles really recovers.
The recovery map and check-in are free. New lifters also get a gentle break-in, with early sessions kept light on purpose while soreness settles. Pro adds pain and soreness patterns over 90 days.
Slept badly? It adjusts.
Every morning, Anneal reads your HRV, sleep, and resting heart rate from Apple Health. With Pro, a low score trims today’s session; a rough day is reshaped into a lighter one, and you see the before and after. It only ever scales back, never past your plan.
Below 40, main lifts go light and accessories become mobility. Tap for the rationale.
Build it. See where it goes.
Build your own program, or save a finished workout as a routine. The engine runs it like any template, and the first session can find your starting weights. With Pro, an 8-week forecast shows where each lift is headed, the likely deload week, and what changes if you train more often. A weekly changelog shows what the engine actually changed.
Progress without the guilt.
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. Going away? Away mode keeps those days off your streak and quiets notifications.
Your gym, audited.
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.

Local-first isn’t a feature. It’s the architecture.
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.
Fair questions.
When can I use it?
Now, on the App Store for iPhone and iPad (iOS 17+), plus Apple Watch.
Can I bring my history from another app?
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.
Do I need an Apple Watch?
No. The Watch adds rest-timer haptics and wrist logging, with reps and weight you can adjust before Done. Siri can log a set too. Everything still works phone-only.
Android?
iPhone first. Excellent beats mediocre on two platforms. We’ll revisit if earned.
How does it know I’m sore?
It estimates each muscle’s recovery from the sets you logged, then asks you to confirm or correct that guess after a session. Your answers tune how fast your muscles recover in its model. It’s a training tool, not a diagnosis.
Is this medical or rehab advice?
No. Anneal trains healthy lifters, caps load jumps conservatively, only ever reducing on low readiness. Pain or injury? See a professional.
Train with a plan you can audit.
Every set planned, every sore muscle accounted for, every weight explained. Free logger forever, no account required.
