Your fuel app tracks gas. We track everything that actually costs you — fuel, insurance, repairs, and depreciation — and turn it into one honest number: your real dollars per mile.

A fuel logger gives you a tidy MPG chart. Useful — but it measures the cheapest part of owning a car. The bill that actually empties your account is fuel plus insurance, repairs, and the resale value bleeding out every month.
You already suspect it: the car costs more than the gas you pump into it. CarTally logs every receipt you'd never keep a spreadsheet for, amortizes the fixed costs over the miles you actually drive, and shows you the one figure that matters — your real cost per mile.
Four instruments, one honest readout. Here's what's on the bench right now.
Fill-ups, repairs, insurance premiums, loan payments, registration, tires. If it costs you money to keep the car, it goes in the log — fast enough that you'll actually do it.
Every fixed and variable cost amortized over the miles you actually drive. One number, updated as you log — the figure your fuel app never gave you.
The biggest cost is the one you never see: resale value bleeding out month after month. We model it in, so the sticker isn't the whole story.
Two cars, a truck and the commuter, the side-gig vehicle — see which one actually costs less to run per mile, and whether the miles are paying for themselves.
Nothing is charged today. This is what we plan to launch — founding waitlist members will hear the final price before anything is ever billed.
