Free Audit-Proof Mileage Log
Most mileage apps either cost money, cap your trips, or rely on GPS auto-tracking that produces records the IRS may not accept as contemporaneous documentation. You should not have to pay for a log that might not even hold up.
MileHawk is a free, unlimited manual mileage tracker built on the method the IRS actually endorses: odometer-based entry at the time of each trip. Log your start and end odometer readings, add a purpose, and MileHawk calculates the miles and stores the record in the cloud. Export any date range as a PDF or CSV whenever you need it — for your accountant, your employer, or an audit response. No subscription, no caps, no GPS required.
Frequently asked questions
Why is manual odometer entry more audit-proof than GPS tracking?
The IRS standard for mileage documentation requires a record of the date, destination, business purpose, and miles driven — logged at or near the time of each trip. Odometer readings provide an objective, verifiable measurement tied directly to the vehicle. GPS auto-tracking captures movement but can conflate personal and business trips and may lack purpose notes, which are required for a valid deduction.
Is MileHawk really free with no hidden fees?
Yes. MileHawk is free to download and use indefinitely with no subscription, no trial period, and no paywalled features. The app is supported by non-intrusive mobile ads. Unlimited trips, unlimited vehicles, cloud backup, and PDF/CSV export are all included at no cost.
Does MileHawk have a limit on how many trips I can log?
No. MileHawk has no cap on trips, vehicles, or reports. You can log every mile you drive across as many vehicles as you own without hitting a limit or upgrading to a paid plan.
How does cloud backup work in MileHawk?
MileHawk backs up your trip data to the cloud so your log is preserved if you lose, break, or replace your phone. When you sign in on a new device, your full history is restored. Your data belongs to you — MileHawk does not sell your trip history or personal data to third parties.
What export formats does MileHawk support?
MileHawk exports to PDF for a formatted, printable report and to CSV for a raw spreadsheet that you can open in Excel, Google Sheets, or import into accounting software. Both formats include date, vehicle, odometer start and end, purpose, and calculated miles per trip.
What mileage rate categories does MileHawk support?
MileHawk includes four IRS rate categories: Business, Charity, Medical, and Military. Each can be used at the standard IRS rate or a custom per-mile amount you set. You can mix categories within a single log — for example, logging both business and charity trips — and filter by category when you export.
What happens to my data if I switch phones?
Because MileHawk uses cloud backup, your complete trip history follows you to any new device. Sign in with the same account after installing on your new phone and your log is fully restored — no manual transfers, no lost data.
