JoltMile is on the App Store

JoltMile is now on the App Store for iPhone and iPad. Download it here (opens in a new tab). It is free to download, and it signs in with the same account as the website, so everything you have already logged is there waiting.

What the app does that the website cannot

• Times your shift. Press Start shift when you set off and End shift when you finish. Breaks are counted, and the wizard opens with the times filled in.
• Measures your miles. While a shift you started is running, your iPhone measures the miles and notes the postcode at each end. It keeps the miles and the two postcodes and throws the rest away.
• Photographs receipts from inside the expense form.
• Reminds you about Self Assessment deadlines without you having to open anything.

Same account, same figures

The app and www.joltmile.com are two ways into one account. Log a shift on your phone in the car park and it is on the website when you sit down at a computer. The figures come from the same calculations in both, so your hourly rate and tax estimate never disagree.

If you already subscribe on the website, that covers the app too, so there is no need to pay again.

Android

The Android app is now on Google Play too. See JoltMile is on Google Play.

The full guide, including how paying through Apple works, is in the JoltMile app for iPhone and Android.

Update, 1 October 2026

Some of this has changed since. Shifts are now logged in the app only, and the website is for exports, receipts and your account: see JoltMile is now a phone app. The free plan is now 12 shifts every calendar month rather than a set number in total.
