Generator Tracker
Read full descriptionHide full description
Generator Tracker is built around what you do during a power cut: start the generator in one tap, keep an eye on it and never miss maintenance — for one backup unit at home, a job site or a rental fleet. START AND STOP FROM HOME • Running generators move to the top with a live timer and a big Stop button; idle ones sit below with Start • Several generators can run at once; a bar at the bottom keeps the running ones a tap away • Stopped by mistake? Undo brings the session back with its original start time • Forgot to tap? Fix the start time or add a session later FUEL LEFT, ESTIMATED • Add your tank size and see roughly how much fuel and how many hours are left • Refills in a few taps: to full, same as last time or a stepper • A full tank calibrates the estimate; consumption per hour is worked out for you • Litres or US gallons — set by your region, switchable in Settings MAINTENANCE ON TIME • Oil, filters, spark plugs — intervals by engine hours, by days, or both • Each task shows how much of the interval is used; overdue work is flagged on the home screen • Mark a task as serviced with one tap CLEAR ANALYTICS • Run hours and fuel by month as bars split by generator colour — petrol and diesel are never summed together • All-time totals and consumption per hour for every generator READABLE DAY AND NIGHT • Warm light theme and a true-black dark theme for OLED screens and night outages • Theme follows the device or can be set in Settings, plus a guide to the system red filter • Native iOS navigation and a comfortable layout on iPad FREE, WITH ONE-TIME PURCHASES • The app is free with ads and up to 3 generators • "Remove ads", "Unlimited" or "Everything" are one-time purchases — no subscriptions • Ads appear only on the Analytics and Settings screens, never around Start/Stop or at launch PRIVATE BY DESIGN • Everything is stored on your device first and works fully offline • An account is optional and only syncs your own records between your devices • Delete your account and cloud data any time in Settings • No analytics, no tracking by the app; ads ask for consent where required • Open source (MIT) — anyone can check what the app does Available in English and Ukrainian.

Generator Tracker's advantage is update cadence (every 5 days vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
