## What is TheLeanFit?

TheLeanFit turns your iPhone's camera into a personal form coach. Prop your phone up, step back and start moving: it counts your reps, scores each one, and tells you how to fix your form while you're still in the set.

YOUR CAMERA IS THE COACH
• Counts reps automatically
• Scores the form of every rep and gives your accuracy at the end of the set
• Spots common mistakes as they happen and calls out the fix aloud
• Draws your tracked skeleton over the camera, so you see what it sees
• Set a target in reps or seconds, and the coach cheers you through the last few

WATCH YOUR SET BACK
• Every set is saved as a 3D skeleton replay. No video is stored
• Drag to turn the skeleton and look at your form from any angle
• Jump back and forth between your mistakes, or pause on any moment
• See your best rep, reps, active time and accuracy after every workout
• Add your weight for a calorie estimate
• Your past workouts in one history, each with its replay

SET UP IN SECONDS
• Quick setup tips for the space, the light and what to wear
• Guided phone placement, and a check that your whole body is in view
• A 3-2-1 countdown, so you have time to get into position
• A guided first rep on the squat: the coach talks you through it step by step

NINE EXERCISES
Bodyweight Squat, Push-Up, Lateral Lunge, Side Plank, Jumping Jacks, Single-Leg Balance, Cat-Camel, Bicep Curls and Arnold Press. Most need nothing but you. Bicep Curls use light weights or a band, the Arnold Press uses dumbbells, and a mat helps for the Side Plank and Cat-Camel.

PRIVATE BY DESIGN
• Everything runs on your iPhone. Camera video is processed on the phone and never uploaded
• No account, no sign-up, no ads
• Works without an internet connection
• Your profile, history and replays are encrypted on the phone, and you can delete them all from Settings

MADE FOR YOU
• Light and dark themes
• A colour-blind-friendly skeleton palette
• Voice coaching in English, which you can switch off

TheLeanFit is a fitness app, not a medical device. Check with a doctor before starting a new exercise routine, especially if you have an injury or a health condition.
