Fuel Pre-Pay Estimator

iOS Universel / Utilitaires

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. Needle sitting 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
• Crop step after every photo so the gauge fills the frame
• Back up and restore your whole garage to a single file
• iCloud sync keeps your vehicles on all your devices
• No accounts, no ads, no tracking — data stays on your device and in your own iCloud

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.
