Simple to use, saves phone battery.

I wanted a simple display with speed, ODO, ride time and the XOSS unit did all I wanted. I know several apps do this, but I wanted to save my phone battery for emergencies on longer rides. The device delivered everything I wanted and the ability to sync to the app was just gravy. App shows me a map of the ride and all the recorded ride data. I can even go back and look at previous rides to see progress. Really like the system. Provides a lot of value and functionality for reasonable price.

App consistently says “GPS Signal Lost” even though Device shows signal

Very frustrated with the XOSS app. After successfully pairing the app with 2 different computers (CYCPLUS and XOSS) and sensors, all appeared as if things were connected and working. I even got the GPS connection to work on both devices, although the XOSS instructions were not as complete as they should be.

However, the XOSS app (iPhone XS, IOS v14.8) consistently says “GPS Signal Lost” as soon as I start moving, even though the G+ shows a strong GPS signal. I’ve researched and tried everything I found online or that I can possibly think of, including Location Services, etc on the iPhone. I’ve not found any similar problem reported in web articles or product forums, and support from XOSS has been marginal at best. If I don’t get some real help and a resolution within the next day I’m going to return both computers and chuck the whole thing.

Again the problem appears to be with the XOSS app on the iPhone, not the XOSS G+ device

Developer Response ,

Thanks for your comments. When you use the XOSS app to record the workout, will it show "GPS Signal Lost" every time? Have you turned on the GPS location permission? Please email the screen recording and more details to "support@xoss.co", so we can see together what's the issue.

The best bike computer ever

I love the fact that I don’t have to put in tire size and align magnets with sensors at proper distances. You connect it to the bars, pair with your phone and go. It’s great and it tracks everywhere you go and the elevation, it will even show on a map your workouts. I Love it, great tool, I wish I had, had one years ago. I would not have wasted so much money on bike computers that are useless now.
