Odo
With prices this high, most people know filling up hurts but have no idea what driving actually costs them. Odo fixes that with one habit: log the pump, and the app does the rest. It works out your true MPG from tank to tank, your fuel cost per mile, and what you're spending month to month - across every vehicle you drive. It is a fuel tracker and nothing else: no maintenance schedules, no insurance, no tolls, none of the vehicle-expense sprawl that every other app in this category drifts into. Logging takes seconds, the numbers are readable at a glance, and everything stays on your phone. No account, no ads, and nothing leaves the device.
Everything it does, nothing it doesn't.
Small on purpose. Each feature earned its place by solving something real.
Log a fill-up in seconds
Odometer, gallons, cost. Three numbers and you're done. Enter whichever two of amount, total, and price per gallon you actually remember and Odo fills in the third.
Your real MPG, not the sticker
Measured tank to tank from what you actually pumped, so it reflects your driving, your routes, and your right foot - not a lab test.
Fuel cost per mile
The number nobody can work out in their head. Odo keeps a running figure so you know what a commute, a detour, or a road trip really costs to fuel.
Every vehicle in one place (Pro)
Car, truck, partner's car, the work van. Each one keeps its own economy, its own history, and its own numbers.
Trends over time (Pro)
Watch MPG drift with the seasons, see what you're spending month to month, and compare this year against last.
On your Home Screen (Pro)
Your average economy and what you've spent this month, on Home Screen and Lock Screen widgets, visible without opening anything.
Cost per mile is the figure nobody can do in their head.
You know what a tank costs. You don't know what a mile costs - and that's the number that tells you whether the long way round is worth it, or what a road trip is really going to run you. Odo works it out from what you actually pumped, and keeps it current every time you fill up. It's fuel cost, not total cost of ownership: Odo tracks what goes in the tank and leaves the rest alone.
No account, no ads, and nothing leaves your phone.
Odo has no sign-up, no sync, and no analytics of any kind - not anonymised, not bucketed, none. Your fill-ups live on your device and nowhere else. Import brings your history in from another app for free, and export takes it back out, so you're never locked in.
Free to start. Pro when you need it.
