Show HN: PunchLab – track punches given to punching bag with an App

Hi HN, we just released an Android App that is able to measure and react to strikes thrown at a punching bag.

Check out https://punchlab.net

It uses data coming from the smartphone's own sensors and analyzes the signal to detect and measure punches.

The App is bag-agnostic and it's able to be accurate enough to track also the fastest athletes (check out this video with a Pro fighter giving up to 7 punches per seconds: https://www.youtube.com/watch?v=nwaHmgj45aQ )

let me know what do you think about it, there are many features we are working on!
