The Squirrel Street Mileage Tracker is available on iPhone.

To use it all you need to do is go to the mobile app.

1) Select Trips from the overview screen.
2) Select Start Trip to begin tracking your trip.
3) Then each time you get out of your vehicle or make a stop simply drop a pin to log that point.
4) Finally just hit End Trip and your milage will calculate using the standard mileage rate and it will appear in your receipts section!

It's that simple, now get out there and start tracking!
