MileStack: Mileage Tracker

Every business mile you drive is worth money at tax time, but only if you wrote it down. MileStack is a plain trip logger for the US standard mileage deduction. You enter the miles, tap a purpose, and the deduction is worked out for you at a fixed per-mile rate for that purpose.

There is no sign-up, nothing running in the background, and nothing leaving your phone. You log a trip in a few taps and get on with your day.

WHAT YOU CAN DO
- Log a trip with miles, a purpose and an optional note
- Sort trips as Business, Medical, Charitable or Personal
- See the deduction for a trip the moment you save it
- Follow your totals at the IRS rate in force on each trip's date: $0.725 a business mile and $0.205 a medical or moving mile to June 30, 2026, $0.76 and $0.235 from July 1, and $0.14 a charitable mile
- Read miles and deduction side by side for each category, with your total on top
- Keep personal driving in the same log without it counting toward the deduction
- Export the whole log as a CSV: date, miles, purpose, rate, deduction, note
- Share that CSV with your accountant or your files through the system share sheet
- Delete a single trip, or clear the log, whenever you need to

WHO IT IS FOR
Real estate agents, rideshare and delivery drivers, couriers, contractors, sales reps, 1099 freelancers and small business owners who file a Schedule C. It also suits volunteers logging charitable miles and anyone tracking medical driving.

PRIVACY
MileStack has no account, no server, no analytics and no advertising. Trips are saved in the app's own storage on your device. The app makes no network calls at all, so nothing is uploaded and the log works with no signal. It runs on iPhone and iPad and follows your light or dark setting.

MileStack is a logger and a calculator. It is not tax advice and it is not affiliated with the Internal Revenue Service. The IRS sets the standard mileage rates, so check IRS.gov for the rates in force for your tax year before you file.
