Like having a personal coach always with you — one that corrects you in the moment, not after. ---- HOW IT WORKS Place your iPhone in front of you, select an exercise, and start moving. The app automatically detects your body position and identifies common form errors — frame by frame, in real time. Kettlebell AI detects key body landmarks (hips, knees, shoulders, wrists, ankles) and calculate joint angles and movement patterns in real time. Each error is classified by severity and displayed on screen the exact moment it occurs. Every session is saved with: rep count, detected errors by category, and a snapshot of your movement with skeleton overlay. Track your progress over time and see exactly where you're improving. ---- WHO IT'S FOR Beginners who are picking up the kettlebell and want to build correct technique from the start. No prior experience needed — the app guides you. ---- FEATURES • Real-time kettlebell form analysis • Instant visual and voice feedback during training • Rep counting and session tracking • Technique issue detection • Post-workout results and insights • Multiple kettlebell exercises to analyze KettleFit AI is designed for people who train independently and want quick feedback on their movement while working out at home or in the gym. ---- CAMERA USAGE The app uses your device camera to analyze body movement and provide technique feedback during kettlebell exercises.
