Best free mileage tracker app: what to look for in 2026
The best free mileage tracker app for Android or iPhone keeps an IRS-ready log: unlimited GPS trips, trip categories, receipts and CSV export. What to look for, and what paid apps add.
September 30, 2026 · 6 min read
Searching for the best free mileage tracker app turns up a lot of "free" trials that cap you at a handful of trips a month before asking for a subscription. If you drive for work — rideshare, delivery, real estate, sales, trades — the right app is the one that records every trip without fuss and gives your accountant a log that holds up. Here is what to look for, what the IRS actually requires, and how to judge whether "free" really means free.
What the IRS expects from a mileage log
IRS Publication 463 asks for records made at or near the time of the trip. For each business trip that means:
- the date,
- the destination (or start and end addresses),
- the business purpose, and
- the miles driven, plus your total miles for the year.
A notebook can do this, but most people forget entries and rebuild the year from memory in April — exactly the kind of log that does not survive a question from the IRS. A tracking app earns its place by making the record automatically. (See our guide to the 2026 mileage deduction for who can claim it and the standard-rate vs actual-expense choice.)
Seven things the best free mileage tracker apps get right
- Unlimited trips on the free tier. A monthly trip cap is a subscription in disguise. Check the limit before you rely on it.
- GPS tracking with sensible battery settings. You should be able to start a trip with one tap and choose between accuracy and battery life. Auto-pause when idle and auto-stop after a long stop keep the log clean.
- Trip classification. Business, personal, medical and charity miles each have their own IRS rate. A good app prices each category correctly and flags trips you haven't classified yet, so they don't silently drop out of your deduction.
- Real addresses. "Trip 14" is useless in an audit. Look for reverse-geocoded start and end addresses.
- Receipts in the same place. Fuel, parking, tolls and repairs matter if you ever switch to the actual-expense method — and parking and tolls are deductible on top of the standard rate.
- Exports your accountant can use. CSV for tax software or a spreadsheet, and ideally a PDF summary.
- Your data on your device. Location history is sensitive. Offline storage with no required account is the privacy-friendly choice.
How to test a mileage app in one week
Install one app, turn it on, and drive your normal week. At the end, check three things: did it catch every work trip, are the distances within a mile or two of your odometer, and could you hand the export to your accountant today? If the answer to any is no, switch now — not in December.
Free vs paid: what the money usually buys
Paid mileage trackers typically charge a monthly or yearly subscription for automatic drive detection, team or fleet dashboards and integrations with accounting software. If you are a solo driver who is happy to tap "start" at the beginning of a shift, a free app with unlimited GPS trips and a clean export covers what the IRS asks for. If you manage employees' reimbursements, a paid fleet product may be worth it.
Our app: Mileage & Tax Expense Tracker
We built Mileage & Tax Expense Tracker for iPhone and Android with that checklist in mind. The free version tracks unlimited GPS trips (Precision, Balanced or Battery Saver modes, with auto-pause and auto-stop), classifies them as Business, Personal, Medical or Charity at their own rates, turns trips into street addresses, and keeps a receipt vault for fuel, parking, tolls and repairs. It handles multiple vehicles, works offline, stores everything on your device, and exports an IRS-format CSV for Schedule C or your CPA. It is supported by ads; a single one-time purchase removes them — no subscription.
Two honest caveats: you start each trip yourself (with one tap), and you set the IRS rate for the year — always confirm the current figure on the IRS standard mileage rates page. We are not affiliated with the IRS and this is not tax advice.

Frequently asked questions
Is there a completely free mileage tracker app?
Yes. Mileage & Tax Expense Tracker for iPhone and Android tracks unlimited GPS trips, applies IRS rates and exports a CSV on the free version, which is supported by ads. A one-time purchase removes the ads; there is no subscription.
What does the IRS require in a mileage log?
For each business trip: the date, the destination, the business purpose and the miles driven, recorded at or near the time of the trip, plus your total miles for the year (IRS Publication 463).
Does a mileage tracker app need an internet connection?
Not for Mileage & Tax Expense Tracker — trips and receipts are stored on the device, so GPS tracking keeps working without signal.
Can I track more than one vehicle?
Yes. Each vehicle gets its own colour, plate, starting odometer and totals, and you pick the vehicle before starting a trip.
Can I use a mileage app for DoorDash, Uber or Instacart?
Yes. Gig drivers are one of the main users of mileage apps because the standard mileage deduction can be large. Classify the delivery miles as Business and keep personal trips separate.
