Ive used this app for almost 3 years now and track my time for payroll, expenses, and mileage. Reporting is fantastic and the interface is great. The GPS tracking is quite accurate although I have had some trips not show up for some reason.
The biggest downfall is battery life. You will need to charge your phone *every* single day. I thought it was my old iPhone 4 getting old, but even my new iPhone SE can barely make it through a day when travelling. And if you shut the app down, it freaks out with a road-runner warning sound. In fairness, the app has to be running constantly to be its most helpful but it would be really handy to have a "vacation" mode or something.
