Voice-guided squat counter that uses your phone's motion sensor to count reps in Greek.

FormCheck turns the phone already in your pocket into a personal squat coach. It listens to your reps in real time, counts them through the accelerometer, and gives the kind of encouragement you would expect from a trainer standing next to you, not a generic fitness app. The dark, minimal interface keeps the focus on movement, making it feel more like a piece of equipment than a website.
