Fuel Tank Switch Timer

Inspired by seeing a kitchen timer in the center console of a modern aircraft — there had to be a better way. Never forget to switch fuel tanks again. Fuel Tank Switch Timer alerts you when it's time to switch fuel tanks during flight — even when your phone screen is off or a navigation app is running in the foreground. FEATURES: • Freely configurable interval (any number of minutes) • Full-screen alarm overlay that appears over any app • Wakes up the screen automatically when the alarm triggers • Audio alarm — plays through Bluetooth headset or intercom if connected • Strong vibration alert — impossible to miss • Simple one-tap acknowledgement to reset the timer • Timer can be stopped at any time • No ads — ever. A clean cockpit deserves a clean app. • Lightweight — runs silently in the background • Works on phones and tablets WHO IS THIS FOR? Any pilot whose aircraft has multiple fuel tanks that need to be switched or monitored regularly during flight. This includes low-wing aircraft as well as any other aircraft where the pilot selects individual fuel tanks rather than flying on "BOTH". HOW IT WORKS: 1. Set your desired interval (e.g. 30 minutes) 2. Tap START — the timer runs silently in the background 3. When the interval expires, a full-screen alert appears, the phone vibrates and an audio alarm sounds — no matter what else you are doing on your phone 4. Tap DONE to acknowledge and automatically start the next interval 5. Tap STOP at any time to cancel the timer completely Fly safely.
