How does Tenths know I’m driving?

Your iPhone’s motion chip and location changes wake Tenths when you start moving. It turns on GPS only to confirm the drive and record the route, then stops once you’ve been parked longer than Merge short stops (Settings › Tracking).

To log drives while the app is closed, set location to Always and turn on Motion & Fitness (Settings › Tracking › Location access).

A drive was missed or split in two

Check that location is set to Always and Precise Location is on. Low Power Mode can delay detection.

Add a missed drive with + on the Drives tab. To join a drive that a long stop split in two, open the second part and choose More actions › Merge with previous drive.

How is my deduction calculated?

Each business drive is multiplied by the IRS standard mileage rate for its date: 72.5¢ a mile from January 1 to June 30, 2026, and 76¢ from July 1, 2026. If your employer reimburses at a different rate, set it in Settings › Mileage rate.

Getting my log out

On the Reports tab, export a PDF log or a CSV for any month, quarter or year (Tenths Pro). Settings › Your data › Export everything saves a full backup at any time, free.

Switching from another mileage app

Export your drives as a CSV from the old app, then open the file with Tenths, or use Settings › Your data › Import from another app. You’ll see a preview before anything is imported.

Subscriptions and purchases

Bought Pro on another device or reinstalled the app? Open Tenths Pro and tap Restore purchases.

To cancel or change a subscription, open the iPhone Settings app › your name › Subscriptions › Tenths Pro. Apple handles billing, so we can’t see or change your payment details.

Deleting your data

Settings › Your data › Delete everything removes every drive, place and vehicle from your iPhone, and from your private iCloud if sync is on. Deleting the app also removes its data from your iPhone.
