Gölbis is a bike rental app developed by YAPIDROM that allows users to sign up by verifying their phone number. Once registered, users can view the nearest bike stations on a map and see available bikes and parking spots. To rent a bike, users must first subscribe and top up their account with credits. They can then go to the nearest station and scan the QR code on the bike using the mobile app to complete the rental process.

The app also includes a usage section where users can view their ride history and evaluate their rides. The payments section allows users to view their payment history, while the announcements section provides access to the latest news and updates.

The menu consists of profile editing, fault reporting, pricing, help, and language settings. Users can report any issues they encounter by taking a photo and submitting it through the fault reporting module.

Users can access the current bike usage rates in the pricing section and learn how the system works in the help section.
