Are there any fitness trackers that don't have a screen and are supported by some OS apps?
I remember researching this some time ago, and there was some abandoned by it's company fitness tracker that people tried to reverse engineer to work with an OS app.
I would like it to have no screen as I already have a mechanical watch, and I dont like to have two things doing the same thing.
Cheers
There's a hackable smart watch. It's got a screen and might not be usable for you for any productivity. Completely open source, as it seems. Called bangle.js 2, not too expensive so you might give it a shot?
That looks very neat. If ever get a smart watch will definitely try this out. Thanks.
