The Tenths home screen: 7,956.6 business miles and $5,867.84 deductible so far this year, with five drives waiting to be sorted.

Drive. Swipe. Export.

Three steps, and the first one is just driving.

  1. Drive like you always do

    Tenths senses the car, records the route, distance and time, and names the places. A quiet notification arrives when you park.

    A recorded drive from Avalon Park to Home on a map: 16.1 miles, $12.27 at the IRS rate, marked Business for an open house.

  2. Swipe to sort

    Right for business, left for personal. Smart rules learn your places and work hours, so most drives sort themselves.

  3. Export a tax-ready log

    A PDF with the date, places, purpose and miles of every trip, or a CSV for your accountant, for any month, quarter or year.

    The 2026 report: $5,867.84 deductible, split into 72.5 cents a mile through June and 76 cents from July, with a monthly chart.

The right rate for every date.

The IRS raised the business mileage rate in the middle of 2026. Tenths applies 72.5¢ to drives through June 30 and 76¢ from July 1, so your deduction is right to the cent.

No account. No servers. Just your iPhone.

Where you drive is nobody else’s business.
