App license

EngineMiles is provided by TooAvid Technologies LLC. The iPhone app uses Apple’s Standard End User License Agreement. Apple’s applicable purchase and service terms also apply to downloads and in-app purchases.

Estimates and maintenance

EngineMiles estimates gasoline-engine miles using the fuel you log and the gas-only fuel economy you enter. Electric-mileage estimates are available for plug-in hybrids with Pro. Results depend on your inputs and assumptions; the app does not read exact engine mileage from your vehicle.

Oil-change estimates and reminders are a guide, not maintenance advice. Follow your vehicle manufacturer’s service recommendations, including time-based intervals, and consult a qualified professional when needed.

Free and Pro

Free includes one vehicle, unlimited manual fill-ups, your engine-mile estimate, history editing, and oil-change tracking. Pro adds the features described on the pricing section.

Pro is available as a monthly or yearly subscription, or a one-time lifetime purchase. US prices are $2.99 per month, $19.99 per year, and $59.99 once. Local prices, taxes, and availability can vary; the purchase screen shows the applicable price before you buy.

Subscriptions renew unless canceled through your Apple Account. Apple manages billing, cancellation, and refund requests. A lifetime purchase does not renew and unlocks Pro for the app; it does not guarantee the lifetime of a device or an operating system.

Private beta

TestFlight builds are prerelease versions intended for testing. They can have bugs, may change, and expire under Apple’s TestFlight rules. Keep a backup of any history you want to preserve.

Your data and support

Your vehicle log is stored locally. Keep your own backups before removing the app or replacing your phone. See the privacy policy for purchase processing and optional usage sharing.
