eGym is a German exercise equipment company that creates smart equipment for gyms. I register with my armband in front of the display and it will immedaitely know my maximum strength for that machine (which it tested), my current training goal and how far along I am with it (which determines the way reps are done) and all my seat settings, which will auto-adjust like in a modern car.

They have an app on Android (and iOS I think) which is unimaginatively titled eGym which shows a lot of this fitness data. An integration with Exist would be excellent.

The website talks about a “platform”, but I can’t find anything about it, so for now this one seems to be not possible. If anyone can point me to API docs etc. I’m happy to move it.
