Travel, and your book fills itself in
Arrive somewhere new and Hirundo stamps it, even with the app closed. Capitals get a star, coastal cities a wave, mountain towns a peak.

Questions
Does Hirundo need the internet?
No. Every country and city is built into the app, so stamping works offline, abroad and in flight mode. Only the App Store purchase and backups you save to iCloud use a connection.
Why does it ask for location "Always"?
So it can stamp a new place when you arrive, which is usually with the phone in your pocket. Hirundo uses low-power location and keeps only the place name and date. With "While Using" it stamps while open, and without location you can stamp places by hand.
A place was stamped wrong. What can I do?
Open the stamp and choose Remove this stamp. Place data near borders, coasts and airports can be off; tell us where it happened and we'll look at it.
How do I move my book to a new iPhone?
On the old phone, go to Settings → Backup → Save a backup file and keep it in Files or iCloud Drive. On the new phone, choose Restore from a backup and enter your password. Then tap Restore purchase to unlock Hirundo forever again.
I forgot my backup password.
Nobody can open the file without it, not even us. That's what keeps it private. Save a new backup with a password you'll remember.
