Yeah, the XOSS G+ is currently designed to interface wirelessly only with Strava and TrainingPeaks. However the XOSS stores activity logs in the G+ device, and the files can be downloaded to a PC, or phone (via email is easiest), and uploaded to any activity app/software that uses standard activity file formats.

I've had to do that a few times when the XOSS phone app failed to sync with Strava. It's a little extra hassle but no big deal. I've done the same thing with MapMyRun to log data from my Under Armour running shoes with embedded Bluetooth sensor in the shoe. MapMyWhatever apps don't sync nicely with Strava so I have to do it manually when I want the extra data from my shoes and the MapMyRun app (footstrike cadence, stride, etc.)..

Another consideration that I try to mention whenever discussing the XOSS -- all data goes through the XOSS servers in China. Yeah, it's basically benign spyware. But I no longer work in any job that demands privacy or security concerns so I'm not worried. If I was still in the military or worked for the government I wouldn't use the XOSS.

I doubt XOSS has any evil intentions. It's just the China way of doing things. I doubt it even occurs to them that they *shouldn't* have access to our data. And originally the XOSS devices were intended to be part of China's own version of Strava (I forget the name of the activity app in China). According to some cycling press reporters in China the original plan was for the XOSS to launch simultaneously with the Chinese alternative to Strava, but the pandemic crisis put that plan on indefinite hold.

And, to be realistic, most of our apps do the same thing. They just don't share it with the US government unless subpoenaed... as far as we know.

If I was really concerned about privacy and security, I'd consider one of the Lezyne computers that requires a USB cord to transfer data -- no wireless sync available. I don't know whether those computers are still available but there were one or two that lacked any wireless connectivity to phones, etc. Or maybe I'd use an old school bike computer, if I was really worried.

Also, Abvio, the makers of Cyclemeter, say their app does not log our data to Abvio or anywhere else, *unless* we choose to do so. By default the data is stored only on our phones.
