At the pump

Opens to the station you're at. Type the odometer, scan the pump display, save.

Correct math

Full-to-full economy. Partial fills roll forward; a missed fill-up never shows a false spike.

Your data

An always-current fillups.csv in your iCloud Drive. Import history from other apps.

Private

No server. Pyrois never sees your fill-ups, your location or your photos.
