Unfortunately no idea, only know Android.
Couldn't help you with this answer but hope you get an answer.

Hello.
The Android version of the Segway-Ninebot application has the same functions as the iOS version (except for Apple localisation).
The application is very limited depending on the serial number. Here, you have a "D" version (Germany/Switzerland).
Most of the menus and functions are not available, such as..:
- speed before start-up (we're stuck at 3 km/h)
- tempomat
- 50% of other functions that you won't even see in this version.
Personally, I changed the box. But the warranty is no longer valid.
