Squat Sensei is an iOS squat counter that uses your iPhone camera and on-device pose detection to count reps automatically. An energetic AI coach delivers motivational voice lines powered by Gemini 3.1 Flash TTS. The app was built with Google Antigravity. Problem: Most fitness apps make you tap to count reps or need extra hardware. Squat Sensei keeps it simple — open the app, squat, and get coached in real time with expressive AI voice.
