Help with Ritvast.

While you're parked, Ritvast uses no GPS. Your phone notices by itself when you drive off: you leave the spot where your car was, or your phone sees you're in a car. Then Ritvast turns on GPS and logs the trip. When you stand still for 5 minutes, the trip is done and you get a notification: business or private?

The trip starts where your car was, at the moment you drove off. Trips shorter than 300 metres or 2 minutes don't count.

Then Ritvast works half automatically: you tap Start trip when you set off, and the trip stops by itself. Want trips to start by themselves after all? Choose automatic in Settings. If your phone won't ask again, Ritvast opens your phone's settings, where you choose Always.

Tap the plus in your trip list. Choose from and to, or tap Same as if you drove that trip before. Add return trip makes the way back in one tap.

Enter your odometer reading now and then. Then Ritvast sees when kilometres are missing and you can explain them right away.

Your odometer makes your log add up: the end reading of one trip is the start reading of the next. GPS sometimes measures a few percent differently from your counter. If you enter your reading now and then, Ritvast adjusts the kilometres to it. If more kilometres are missing, Ritvast asks you to explain them.

Yes. Open the trip and tap Edit. You can also split a trip, merge two trips, add a return trip or move a trip to another car. Ritvast keeps what it said first. In the PDF that trip gets an asterisk and the list of changes is at the back.

Go to Export, pick the period and the file: PDF, spreadsheet (CSV) or expense claim. Tap Export to share it, or Send to your accountant to email it right away.

Your trips are in your phone's normal backup: iCloud on iPhone, Google on Android. When you set up a new phone from that backup, your trips are back.

You can also make your own backup file at Export. Keep that file or send it to your new phone and choose Restore a backup there. That also works from iPhone to Android and the other way round.

In Settings, at the bottom: Erase all. That erases all trips, cars, readings and places on this phone and can't be undone. Save your yearly PDF first. Nothing is stored with us, so there's nothing to erase there.

Then this version is too old to work well. Update Ritvast in the App Store or Google Play. Until then, Ritvast keeps logging your trips, and you can still export them from that screen.
