Currently used it.. the Chinese market one... but end of last year it's automatic updated to enlish a.k.a global version when synced with mi fit due to language setting in mi fit apps... but with android.
A decent smartwatch... battery tahan for a week... battery charged fast.
Using it as normal watch + 1hr daily to count my workout.
3% battery still can tahan for more than a day.

compatible apps mi fit... but can link with strava/endomondo via 'Fitness & Notify for Amazfit' (paid - USD2.99) apps.

bip only got one version other market call it bip lite / youth / youth lite imho.

not sure on location... but I think it follows the language you setup for your mi fit apps.
