YMMV — Your Mileage May Vary — is a beautifully simple iOS app for tracking every fuel fill-up for your vehicle, and understanding exactly how efficient your vehicle really is.
A focused set of features built around one goal — helping you understand your vehicle's real-world fuel efficiency over time.
Log every fill-up with miles driven, gallons, total cost, cost per gallon, station, and notes.
Track average, best, and worst MPG. Visualise trends with interactive area charts over time.
Monitor total spend, average cost per gallon, and your lowest-ever price at the pump.
Import historical data or export your entire fill-up history as a standards-compliant CSV file.
Instantly find any fill-up by date, location, miles, cost, or gallons. Sort newest or oldest first.

Getting started takes seconds. Three tabs — Fill-ups, Statistics, and Data — keep everything within reach.
Tap + or scan a receipt with your camera. Enter miles driven, gallons, and cost. The app auto-calculates cost per gallon.
The Statistics tab instantly shows your average, best, and worst MPG alongside total miles, spend, and an efficiency grade.
Use the Data tab to share your history as a CSV or import data from another app. All data lives on your device — no accounts required.
YMMV is built entirely with Apple's modern frameworks — no third-party libraries, no external tracking, no subscriptions.
