Edit 2026-11-01: GrapheneOS is allowed now and works, but the app insists on password only as authentication (biometrics are disabled and I get a warning about Play API). In other words, the most secure mobile OS is not good enough for TK but Android and IOS are. One step forward two steps back.

Worked fine for years, suddenly blocks me at login for "security" reasons. It says my device is rooted, it's not. I use a Fairphone 5. It's a shame that to use essential services, TK blocks people from using repairable, sustainable devices. Even if it were rooted, it's none of their business. my device's security is my problem, worry about your own app's security and leave it to that. I already contacted support and they just repeat the security excuse with no justification.

Not sure if it's on this end, but TKFit is not counting cycle km if I track with my Fitbit Air on or automatic tracking (my phone is also in tracking) . It only counts cycles when I start tracking only with my phone. Update: Still problems with tracking. Suddenly it cuts tracking distance for cycling. I manually tracked 11km, the app showed 11km, but the next day it cut it to 8km.
