KeptMiles: HMRC Mileage Tracker
Every mile counts. Every mile tracked.
Everything unlocked until 5th April 2027 (end of 26/27 tax year)
All Premium features are free during the launch period: unlimited journeys, PDF reports, cloud backup, charts, and more. No account required, no card needed. Just install and start tracking.
What is KeptMiles?
KeptMiles is a free Android app that automatically tracks your business mileage and calculates your HMRC mileage allowance claim. It uses GPS to detect when you're driving, logs every journey, and applies the correct Approved Mileage Allowance Payment rates: 45p per mile for the first 10,000 business miles and 25p after that. Built specifically for UK sole traders, contractors, landlords, and employed staff who use personal vehicles for work.
Once installed, you don't need to think about it. KeptMiles runs quietly in the background and picks up each trip as it happens. At the end of the day, your journeys are waiting for you to classify. Tap business, personal, or commute, and the mileage claim updates instantly. Set up saved locations for regular destinations like client sites or your workshop, and those journeys are classified for you automatically.
When your accountant asks for mileage records, or Self Assessment season comes around, everything is already there. Generate a PDF or CSV report covering any period you need, with every journey, distance, rate, and claim amount laid out clearly. No scrambling through diaries, no guessing, no spreadsheets.
Why KeptMiles?
What makes it different from other mileage trackers
Designed for the UK from Day One
KeptMiles isn't a US app with British settings patched in. HMRC's 45p/25p rates, the 10,000-mile threshold, and the 6 April tax year are all baked into the core, not buried in a settings menu. Reports are formatted the way UK accountants expect them.
Automatic Detection
Forget to start tracking and your journey is lost. KeptMiles detects driving automatically through GPS and activity recognition, so you never need to open the app before setting off.
Privacy-First, On-Device Data
Your journey data stays on your phone. There are no mandatory accounts, no cloud syncing by default, and no data harvesting. Optional Google Drive backup is available if you want it, but it's entirely your choice.
Free to Start
Track up to 20 journeys per month at no cost, with full access to automatic detection, classification, route maps, and the tax year dashboard. Premium adds unlimited journeys, exports, charts, and backup, but the free tier is genuinely useful on its own.

Accurate Threshold Handling
When a journey crosses the 10,000-mile threshold, KeptMiles splits the rate correctly: part at 45p, part at 25p. Most apps apply a flat rate and get this wrong.
UK Tax Year Aware
Tracks the 6 April – 5 April tax year automatically. Your totals, charts, and reports align with HMRC's calendar.
