Support for the Fossil Hybrid HR is really good in @gadgetbridge , including and awesome watch-face designer. Thanks to the very dedicated team for all the work! Gadgetbridge has pretty much feature-parity with the original app including workouts (done by integration with #OpenTracks ) and even few more extra things, like custom Android Intents or button configuration. You can check out the very nice wiki page [1], describing the support.

@th @gadgetbridge wait, you can build watchfaces for this thing? Next you'll tell me apps are possible too!
