I'm recovering from a broken leg, so I can't easily follow a normal Peloton class.
There are guides for running non-Peloton applications on the tablet (which runs Android), but there's no way to keep track of any of my stats.
So I reverse engineered the official applications and found a route to send serial data to and from the bike's sensor module. From there I was able to retrieve live stats, and wrote an app that overlays those stats over other apps
The result is being able to watch content from any app that runs on Android while still getting the same live metrics as you would within the Peloton app
