horrible, please use any other service
The UI is clunky, and more than that the app has a lot of shady practices. I bought a bike pass for 4$, thinking I could use it on any bike - lo and behold, it’s not applicable on the bike nearest to me (a premium bike). Then, since I can’t unlock without having credit in my wallet, I top up 10$ and try to unlock again; the app now complains that this kind of bike can only be parked in the green zone: which this bike is not in to begin with! The green zone was very far from where the bike was parked, so it defeats the transportation aspect of the bike. Finally, when I bought the pass, I noticed a while later that the app had subtly turned on auto-renewal - absolutely horrendous.
