Mount your phone on the mirror. A live 3D avatar mirrors every rep while the camera counts, checks tempo and corrects your form — with your heart rate in the loop from your smartwatch. A training programme tailored to your goal, equipment and body, and fat loss that keeps the muscle with no calorie counting. One payment for the trainer; no subscription for the basics.

Camera form-checkers draw dots on a video. Programme apps don't watch you at all. FormFlect does both — and the bits in between that make it work in a real gym or hotel room.
Not a skeleton of dots: a full-body avatar that moves as you move, translucent so you still see yourself. Depth, tempo and symmetry are visible at a glance — the way a trainer sees you.
Suction-mount the phone to any mirror. Stand where you'll train; the camera reads you and works out the angle it needs. Walk back, line up two circles — hot-and-cold beeps guide you — and it's aimed. Hotel gym, home, anywhere with glass.
Reps counted, tempo checked, form cues spoken in a voice you choose. Heart rate from your watch keeps effort in range. Ask the coach anything by voice — "something for shoulders with dumbbells" — and it pulls up exercise cards and alternatives for what you can't do.
Goal, experience, days, equipment, what hurts. A structured block that progresses week to week and adjusts to what your data says — sleep, activity already done today, how the last session felt.
Five numbers — weight trend, protein, steps, lifting, sleep — read from Apple Health (MyFitnessPal, your Watch, your scales). Timed prompts with real figures: "104 g protein to go, tuna on crackers", a snack before your weak hour, last coffee before the cutoff.
Pose tracking runs on the phone; video never leaves it. No account needed for the trainer. Bring your own AI key for the coach if you like — or let FormFlect+ include it.
Session views are illustrations of the live overlay on models; the remaining screens are real captures from the current build.
Library footage with FormFlect’s avatar tracked onto it, frame by frame — the same pose engine that runs on the phone. The clips show you the shape before you start; the camera then coaches you to it.

Not because calories don't exist — because counting them is a bad instrument, and it measures the wrong thing.
Labels are allowed to be 20% out. People under-log what they eat by a fifth to nearly half. "Calories burned" on your wrist is a guess. You're doing arithmetic on numbers that were never real — and most people quit it inside twelve weeks.
A small deficit held for months beats a big one held for weeks. Crash diets take muscle with the fat, drop your daily movement by 200–400 kcal, and set up the rebound. FormFlect watches your weight trend and keeps you in the band — adding food if you drop too fast.
Muscle is what keeps weight off and what the mirror shows. Enough protein at every meal and two or three lifting sessions a week are the two best-evidenced ways to keep it while fat goes. Those are the things we track.
A structured block from your intake, coached in the mirror by the camera: reps counted, tempo checked, form corrected, Apple Watch heart rate in the loop. It progresses week to week.
Weight trend, protein, steps, sleep, sessions, how hard they felt — and everything Apple Health already knows. When something drifts, the app says what to change and why: more food, a lighter week, protein earlier. Adjustments from evidence, not willpower.
Read from Apple Health (MyFitnessPal, your Watch, your scales all feed in) or logged in seconds. Notifications carry the live figure — "104 g protein still to go, tuna on crackers" — timed to your day: before your snack window opens, an hour before you train, last coffee before the cutoff.
FormFlect does the thing neither does: helps protect muscle while the fat goes, and changes the training programme when your data says to.
"The best diet is the one with enough protein, enough total food, mostly whole foods, that fits your life." — what the evidence-based coaches actually say. We built the app around it, and we show our working: every claim graded against the research on the evidence page.
We don't think "a camera counts my reps" should be a subscription. The trainer is yours once. The parts that cost us money every month — nutrition data, notifications, an included AI coach — are the only things that renew.
Launch price for the first 30 days after release, then $34.99. Family Sharing supported.
Cancel any time. The trainer keeps working without it.
Because the trainer doesn't cost us anything after you've bought it — pose tracking runs on your phone. Subscriptions should pay for things that keep costing: that's Fuel's data and notifications, and an AI coach we pay the inference for.
No. Paste your own OpenAI-compatible key in Coach settings and the voice coach is free. FormFlect+ is for people who'd rather not set that up — we include the model.
An iPhone (Android to follow), a mirror, and ideally a suction-cup phone mount with a ball joint (any windscreen mount works). A smartwatch adds heart rate; it isn't required.
