Start begins the trip meter and the clock. Pause holds both without ending the trip. Stop ends it and leaves the reading on screen, so you can log it or reset the meter back to zero.

What to save

A route The roads between two addresses, with a margin either side for detours. The smallest and usually the right choice. An area The rectangle shown on the map to the right, at full street detail. Pan and zoom it to frame a city or a metro. The whole map Every country at major-road detail, about 1 GB — enough to orient anywhere, not enough to read street names. Save routes and areas on top for the places you actually drive.

Pick what to save and the size appears here before anything downloads.

Saved tiles keep the map drawing with no signal. Fresh address search and turn-by-turn still need a connection; with none, the address fields fall back to places already in your logbook.

Area to save

Used by the "an area" mode: whatever this map shows is what downloads.

Units Taxpayer name (appears on the report) Starting and stopping Stop the trip by itself after standing still for Judged on position, not speed: any real movement restarts the clock, while GPS jitter does not. At a place I have named, stop after Standing still at a place you named is not ambiguous the way standing still at a level crossing is, so arrival is settled sooner — and the destination is filled in by name instead of guessed from the map. Counted as being at that place within

Auto-stop ends the recording and keeps the reading on screen — nothing is logged until you say so. It cannot start a trip by itself: no browser is allowed to watch GPS while closed.

Named places

One-tap addresses for the places you actually drive: home, the shop, regular clients. Marking one as Home and one as Work lets the app spot commutes, which are not deductible.

Deduction rates

Rates are per category and effective-dated, because the IRS changes them — 2026 split mid-year (business 72.5¢ then 76¢ from July 1). Every trip is valued at the rate in force on its date. The table ships with the published IRS figures; verify against irs.gov each January.

Your data

Everything is stored on the machine running this server, under your account. The exports are plain CSV that any spreadsheet or accountant can open.

The PDF covers the vehicle and tax year picked at the top of the screen: odometer readings, totals and deductions by category at the correct split-year rates, every trip, any odometer photos, and a signature line.
