Generator Tracker 3.1.0

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; litres per hour are worked out for you

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 litres 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
