Fuel Pre-Pay Estimator Live

Fuel Pre-Pay Estimator tells you exactly how much to pre-pay to fill your tank — so you don't overpay the clerk or come up short at the pump. It works the way you already read your fuel gauge. Snap a photo of your gauge, fill up, and record how many gallons it took. Do that a few times and each vehicle builds its own calibration library — gauge photos, each tagged with the gallons needed to fill from that point. At the pump, open the app, tap the saved photo that matches your needle right now, enter the price per gallon, and you get the dollar amount to pre-pay. If the needle sits between two photos, select both and slide — the app interpolates the gallons for you. FEATURES • Multiple vehicles, each with its own photo and gauge calibration history • Match your current gauge to a saved photo, or interpolate between two • Optional pre-pay buffer (+$1, +$2, +$3, or +5%) so a creeping pump doesn't cut you off short • Remembers the last price you entered • Tap any gauge photo to zoom in for a clear read • A crop step after every photo so the gauge fills the frame • Back up and restore your whole garage to a single file — the same backup file works on iPhone too • No accounts, no ads, no tracking — your data stays on your device Built for anyone who prefers to pre-pay with cash, sticks to a fuel budget, or just wants to walk up to the counter knowing the number.
