Coming soon to the App Store
Slashie: Mileage Tracker, for iPhone (iOS 26 or later).
No account neededYou run more than one business. Slashie records every drive, works out which job it was for, and hands each business its own tax-ready mileage log.
That is the IRS business rate for Jul–Dec 2026, and it adds up quickly. Drag the slider to see a year of your driving as deductions.
A deduction lowers your taxable income; it isn't a refund.
An example split. Slashie keeps the real one, drive by drive.
Most mileage trackers ask one question: business or personal? But you sell houses, rent out event gear and flip storage units. One “business” pile leaves you splitting a year of drives between three businesses from memory, and the ones you can't place get left out.
In Slashie every job is a slash. Type yours once, and each drive is filed under the job it was for.
Which business? You'll work that out in April.
Filed when you parked, with “Showing” as its business purpose.
Export any slash for a month, a year or a custom range, as a PDF or CSV. Every drive carries its date, times, addresses, miles and business purpose, priced at the IRS rate for its period.

Type your slashes once. After that, Slashie works from three things you already have.
When Slashie isn't sure, the drive waits in your Inbox with a suggestion. It never guesses on your tax log.
No dongle, no buttons. Slashie uses the sensors already in your iPhone.
It pairs with your car's Bluetooth and starts warming up GPS before you pull away.
It logs GPS points while you drive and snaps them to roads, so the miles are measured instead of estimated.
A Live Activity and Dynamic Island show the current drive, and two buttons sort it before you park.
There's no account and no sign-up, and nothing is sold. Your trips live on your iPhone and sync only through your own private iCloud. Slashie reads your calendar on this iPhone to work out which job each drive was for. Event titles are saved only with matching drives in your private iCloud; event addresses are looked up with Apple Maps. Nothing is sent to us.
