GPS speed, trip information, HUD and GNSS receiver status work without an OBD adapter.
Skorost started as a GPS speedometer. It is expanding into tools for performance testing, vehicle diagnostics and saved vehicle history.

A speedometer, performance timer, scanner and vehicle log work better when they use the same interface and share related history.
GPS speed, trip information, HUD and GNSS receiver status work without an OBD adapter.
Acceleration, braking and lap timing turn GNSS data into performance sessions that can be reviewed later.
Compatible OBD-II adapters add trouble codes, readiness, live data and carefully scoped enhanced diagnostics.
Garage and session history keep vehicle, route, service and diagnostic details after the drive.

The Android app is available now on Google Play. The planned iOS version will follow the same product structure and visual identity as closely as practical while using native iOS technology and platform behavior.
That means one Skorost product, not one cross-platform codebase pretending both operating systems are identical.
Skorost separates confirmed support from planned support. Scanner coverage expands only through verified diagnostic profiles. Manufacturer functions that change vehicle state are shown only after they are intentionally implemented and validated.
