Travel: Stats tracker
Get in touch: beiserjohannes@gmail.com. One person reads it, usually within a few days. A screenshot helps more than a description; if a figure looks wrong, say which screen and which trip.
On your iPhone and in the private database of your own iCloud account, which syncs it to your other devices signed in to the same Apple Account. Settings → iCloud shows the sync status. Nobody else, the developer included, can read it.
Settings → Data → Export backup writes a readable JSON file with everything, banknote photos included; Send a copy shares the same file by AirDrop, Mail or Messages. Import backup reads it back, either merged with what is there or replacing everything, and shows you what will change before it does.
A country counts as visited when a trip has a stay there. Home countries, added in Settings, count as visited from the date you moved there, but never add days traveled. Days are counted inclusively, so a trip from Friday to Sunday is three days.
Both are off by default. Turn one on in Settings → Features. They share the tab bar's last place, so turning one on turns the other off.
Add it in Settings under Custom airlines or Custom airports. It then appears in the pickers and on the map, and syncs like your trips.
Rates are fetched from public services when you open a country, at most about once a day, so the first time needs a connection. Otherwise the app shows the last rates it received.
Swiping a record away offers Undo for a few seconds. Past that, the way back is a backup, which is the argument for exporting one occasionally.
If a number looks incorrect, that is worth an email. Include the screen, what it shows and what you expected. An exported backup makes the cause much easier to find, but it holds your whole travel history, so only send one if you are comfortable with that, and never post one publicly.
