in action.
A closer look at every screen — the living 3D muscle model, adaptive workout plans, effortless meal and water tracking, a private Health readiness dashboard, progress you can actually see, and a full workout on your Apple Watch. These are real screenshots from the FormTwin app on iOS, iPadOS and watchOS.
Your whole health, in your pocket
From a rotatable 3D body to a weekly meal plan, everything FormTwin does lives one tab away on iPhone. Tap any muscle to see how to train it, build a plan around your goal and schedule, log food in seconds, and check your recovery before you push.
More room to see the whole picture
On iPad, FormTwin spreads out into a full-screen 3D model and a side-by-side layout, so your plan, nutrition and progress are all in view at once — perfect for planning your week or reviewing how far you've come.
Run the workout from your wrist
Today's session syncs to your Apple Watch automatically. Start it on the wrist, tick off each set as you finish, let reps auto-count, and rest with a built-in timer — all with live heart rate and calories, no phone needed.
FormTwin in motion
The 3D body, an adaptive plan, a live tracked workout and effortless food logging — the whole loop in under half a minute.
Every screen, working toward one thing
FormTwin is a workout, nutrition and 3D-anatomy app for iPhone, iPad and Apple Watch. The screenshots above show how it fits together: your training turns into a living 3D body you can rotate and see through, so the muscles you work actually light up. Tap any of the 28 muscle groups and FormTwin shows what it does and the best exercises to grow it, drawn from a library of 129 movements mapped to your anatomy.
The workout plans adapt to you: pick a goal and how many days you can train, and FormTwin builds a Full Body, Upper/Lower, Push-Pull-Legs or Bro split. A rolling schedule moves today forward when life gets in the way, so a missed day never breaks your streak. On Apple Watch, that same plan is on your wrist — start it, tick off sets, count reps automatically and rest with a built-in timer while your heart rate and calories are saved to Apple Health.
The nutrition screens make eating well simple: log a meal with an emoji food picker, a barcode scan or a photo analysed on-device, in exact portions — grams, millilitres or "3 eggs" — and track water in litres with your own bottle sizes. The Health readiness dashboard reads Recovery, Sleep and Strain from Apple Health, and progress charts turn weight, body composition and streaks into something you can finally see. Everything stays private: no ads, no trackers, on your device and your own iCloud.
