Polarity Dispenser

Open Source Web Application for tracking push-ups with your smartphone cam. It works by placing your phone on the ground, turning on the camera, and it tracks how many push-ups you do based on the up-and-down movement, so you don’t have to count them yourself. I had an iOS app for this, but it costs money and they want a monthly subscription. I thought, no way, I’m not into that just for counting things. So I decided to create a web app myself, and that’s exactly what I did.
