This simply doesn't work. I connect my speed and cadence sensors to it, no problem. When you record a ride, all the readings are 0 and stay that way. It picks up my cadence, and that shows, but everything else is 0. It has GPS that shows where I am and moves with me. I've tried reinstalling and setting up a new account, but it's still the same. it's a pity as I like the ability to plan routes

Version 3.20.0 has problems, can't download workouts. I contacted support and they are working on a new version to fix the problem. If you are having this problem email support from the app and you will be sent a link to the previous working version of the app in an auto respond email. Then just download it, delete Xoss app and re- install using the downloaded version. I did this and recovered my missing rides

The device is fine, works, is a good price, and the battery lasts forever, unlike even basic Garmins. It's annoying you can't download gpx files directly from the device, but as it syncs via the app to Garmin, that's not insurmountable. For some annoying reason, the ability to change the time zone on the app has disappeared on the latest update. You can adjust on the device, but much clunkier to do so, and annoying.
