Mobile & fullstack developer from Ukraine · building Generator Tracker

Yuri Valigursky • Peerlist

Generator Tracker is a logbook for power generators. Scheduled blackouts in Ukraine turned generators into everyday appliances — and engine hours, oil changes and fuel are easy to lose track of, especially since most portable generators have no hour meter.<ul><li>One tap to Start/Stop: engine hours count themselves; several generators can run at once; Undo a mistaken Stop</li><li>Fuel left and runtime estimate from the tank size; litres or US gallons per hour from your refills (switch in Settings)</li><li>Maintenance by engine hours, days or both — overdue tasks show on the home screen</li><li>Monthly charts of hours and fuel per generator</li><li>Big buttons for the dark and a true black theme that saves battery during outages</li><li>Offline-first: data stays on the phone; an optional account only syncs your own devices</li></ul>Under the hood: offline-first sync with pending state instead of a queue, tombstones for deletes and a pure last-write-wins merge, covered by unit and emulator tests.
