Mobile app for a sharing station network
We developed a client app for renting and managing shared power banks. The app works in real time with IoT stations over WebSocket and REST API.
Real-time device state sync with minimal latency, operation over unreliable mobile internet, and handling rental edge cases.
We took all of the client’s existing groundwork and turned it into a production-ready mobile app that supports more than 1,000 sharing stations. The system holds its own against the market leaders and is set to roll out to new Russian regions.
