Every trail, measured on your iPhone.

Drop pins on a map and TrailTally measures the distance — following real trails and roads when you want, or a straight line when you don't — then multiplies by however many laps you did. Prefer to just go? Hit Record and it tracks your route as you move, the same way, right down to asking when a trail forks and it's not sure which way you took.

What's inside

Follows real trails

Routes along roads and paths instead of a straight line, using OpenStreetMap trail data.
Asks when it's not sure

When paths fork or run close together, TrailTally shows both options in different colors on the map and asks which one you took.
Straight-line legs

Switch any leg to a dashed straight line for open fields, beaches, or water crossings.
Laps and out-and-back

Measure one loop and multiply by however many times you did it, down to half laps for out-and-back days.
Record your route

Track a GPS route in the background, screen off, with live distance, time, and pace.
Picks up where it left off

If the app closes mid-recording, resume with your track intact instead of starting over.
A library of your routes

Every saved route gets a small map preview and a name, searchable later.
Export as GPX

Share any route as a standard GPX file to use anywhere that reads one.

Paid apps, just like the old days

TrailTally costs a nominal price on the App Store, and that's the whole deal — no ads, no subscription, no in-app purchases, no accounts, no analytics or tracking SDKs of any kind. Where it's a little different from the other apps here: measuring a route needs map imagery from Apple, and following real trails needs road data from OpenStreetMap — both need a moment of network access, honestly disclosed rather than glossed over. Everything else — snapping to the trail, doing the math, deciding when to ask which fork you took, recording your GPS track, and storing what you save — runs entirely on your iPhone, and stays there unless you explicitly export it yourself.

How TrailTally actually handles your data: Map tiles, from Apple · Trail data, from OpenStreetMap, only when needed · Location access, When In Use only · Everything else runs on your iPhone · No account, no third-party SDKs · Anonymous diagnostics via Apple's MetricKit, opt-in · Recorded routes stay put unless you export them.
