7 issues- Everytime you try logging in the app just glitches anyways can’t even get logged in.
- Comparing to others frequently fails
- Compare to friend feature way to frequently fails with the message about the tracks not matching well enough despite being the same track on the same days even.
- New version is off
- It won’t let me compare the laps with other friends on the same day. Says lap not similar. Literally same day same track same session.

- Friend integration is currently pretty lacking. When I try to compare laps it complains that the tracks aren't similar enough.
- Worse though is that there's no apparent way of sharing your sessions with friends.
