Generator log vs Generator Tracker

Do you have a generator? Tired of recording its working time? Don't remember last changing oil time? Then this application is going to simplify its service for you. Just imagine a notebook with such a possibility to mark the beginning or end of work with one click. Timely maintenance work is going to allow you to increase the engine life significantly helping you to avoid expensive repairs.

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.
