Build muscle. Get lean.
The research, applied to you.
A lift that won't budge. No straight answer on what to eat. No idea which muscles are falling behind. One app handles all three.
Research-grounded custom training program
Built around you by AI. Checked before you lift.
AI writes every workout from your past lifts, goals and injuries, using a summary of published muscle-building research. Then each plan is checked for enough weekly sets per muscle.
See the rules it followsCustom nutrition tracking
Targets built for your body. Meals logged in a sentence.
Type a meal the way you'd say it, or snap a photo of the plate. Calories, protein, carbs, fat and fibre come back, and recent foods log again in one tap.
AI body-photo analysis
Your photos show what's lagging. Your workouts target it.
The AI compares your older photos with your newest and ranks your weakest areas, like upper chest or rear shoulders. Each workout then targets the top one that fits the day.

What to lift. What to eat. Where to focus.
Most people juggle a workout app, a calorie app and a camera roll that never talk to each other. Here all three live in one account. Your past lifts set your next weights. Your weigh-ins steer your calories. Your photos decide what to work on first.
Research-grounded training
Written by AI from a summary of published research
Your week is planned muscle by muscle to reach a research-backed weekly minimum of sets, in four-week blocks ending with a lighter recovery week. By default a second AI reviews each plan, then the app checks it against those minimums and your exercise count. A plan that falls short gets a repair pass when time allows, and you can see whether it passed.
- Hit the top of your rep range on every set and the weight goes up; stalled lifts get a jump or a swap
- Fitness class tomorrow? Today's workout goes easy on your hamstrings and calves
- Pick how long you have, or no limit; extra sets are trimmed to fit, never your minimums
- Injuries and exercises you rule out are hard rules the AI must follow in every plan, review and swap
Custom nutrition
Your numbers, with the reasoning shown
Your calorie, protein, carb, fat and fibre targets come from your bodyweight, height, age, sex, goal and training days, and the reasoning is shown. Weigh in most mornings and the app compares your weight trend with your goal, then suggests whether to change calories, which way and by how much.
- “3 eggs, oatmeal with a banana, shake with milk” is a complete entry
- The portions it assumed are shown before you confirm anything
- No calorie change is suggested until enough weigh-ins back it up
- How often you hit your protein, and your weekly calorie average
AI body-photo analysis
Honest feedback, turned into workouts
Muscles don't all grow at the same rate, so it pays to know where you're behind. Upload front, back or any angle whenever you like. The AI's report starts with your weakest area and says plainly what hasn't changed. Each workout then targets the top-ranked weak spot that fits that day's muscles.
- Weak spots ranked worst first and named by body part
- The exercise picked for a weak spot says so in its coach's note
- Honest, not flattering, and upfront when lighting or angle makes photos hard to compare
- Optional, visible only to you, and iPhone HEIC photos are converted for you
What it does
A coach that reads your logs
Every session is built from the weights and reps you actually hit — not a template. Hit the top of your rep range on every set and the load goes up next time. Stall for two sessions and it forces a jump or swaps the movement.
Four weeks of trend, not one day of noise
Total work per week, work per muscle week by week, and an estimated one-rep max per lift. Deload weeks are excluded from the direction, so a planned easy week never reads as a decline.
One dashboard for both halves
Training and food meet on one screen: muscles still under their weekly minimum, lifts that have stopped moving, how often you hit your protein, your weekly calorie average and your bodyweight trend.
Calories that follow the scale
Training hard on the wrong calories is wasted work. Weigh in most mornings and, once there are enough readings, your weight trend is measured against your goal to tell you whether to eat more or less, and by how much.
Swap anything, mid-session
Machine taken? Shoulder cranky? Swap one exercise for another that trains the same muscles at a sensible load, and keep logging the rest while it works. Or replace the whole session.
Logging that stays out of the way
Your prescribed numbers appear greyed in each field. Press Enter to log them as-is, or type what you actually did. The exercise turns green on its own when it's complete.
Sessions timed end to end
Start the workout, complete it, and the delta is kept. Time per set — rest included — is the quietest reason a lift stalls, and it is one of the few numbers nobody tracks.
Your limits are hard rules
Tell it what your body can't do — bad back, cranky shoulder, no barbell work — and those movements, in any variation or under any other name, are hard rules the AI is told never to break in any session, review or swap, and the audit checks for them.
How injuries are handledFour AI agents, each with one job
Most fitness apps ask a model for a workout and print whatever comes back. This one puts the draft through review by default before you see it, and says so when it didn't, because a coach that never checks its own work repeats its own mistakes.
The Programmer
Pulls your logged history, this week's sets per muscle so far, everything already planned for the rest of the week, and your progress photos. Then writes the session.
The Auditor
A second pass re-reads that draft against a checklist: is progression real, was anything stalled ignored, does it break a constraint, is a muscle group missing, is the rest adequate. It corrects what it finds and tells you what it changed.
The Swapper
On demand, mid-workout. Replaces one movement with an equivalent that hits the same muscles, avoiding anything already in today's session, at a load drawn from your own history.
The Meal Reader
Turns a sentence or a photograph into calories and macros, states the portion it assumed, and waits for you to confirm before a single number is saved.
