A Nextbike client without Google Play service dependencies.
The only feature from the normal app that is not available is the booking via the map (no Google Maps, bikes must be booked via QR code) and thus the reservation function.
The rest works without any problems.
This is their website:
https://www.nextbike.net/en/
They operate in Europe.
Cool. That gives people context about what this FOSS app does for them.
Thanks for adding that info.
