See which app pays you most per mile, once the miles between apps are counted.
Every mileage calculator on the market — including our own Mileage Deduction Calculator — answers one question: what can I write off. None of them answer the question multi-app drivers actually have when they're deciding how to spend their week: is Uber or DoorDash the better use of my miles right now?
We don't answer that with a published per-mile rate, because there isn't one that's honest. What an app pays per mile shifts by city, by hour, by surge — the moment we printed a number, it would already be wrong somewhere. Instead, you tell us what each app actually paid you and how far you drove for it. That's your data, it's accurate because it's yours, and no competitor can reproduce it because every competitor only sees one app's side of your week.
You drop off your last Uber rider. You start driving toward wherever DoorDash orders are actually clustering tonight. That drive isn't in Uber's trip history — the ride already ended. It isn't in DoorDash's either — you haven't accepted an order yet. It's real driving, on a real business day, and it's still a deductible business mile. It's just invisible to both apps.
Multiply that gap by every app switch in a week and it adds up to miles most drivers never claim — not because they're not allowed to, but because nothing was tracking them. This calculator works that number out from your odometer readings and folds it straight into your deduction, using the same country rates as our standard mileage tool.
