Need help with HamsterDB? You're in the right place. All support is handled directly by the developer.
When you tap "Add Station" and enter a US callsign, the app automatically fetches name, location, and license class from Callook.info. The data is saved locally — no account required.
Callook.info does not provide email addresses in its public lookup. Use the QRZ.com lookup, copy the full result, and paste into the QRZ field. HamsterDB will automatically extract the email and other available fields.
Go to the Export screen, choose "Export to JSON". The file can be AirDropped, emailed, or shared via any app. The recipient simply uses the Import feature in HamsterDB.
Yes. Everything is stored only on your iPhone using SwiftData. No cloud, no analytics, no tracking. Apple's privacy report will confirm zero data collection.
Make sure you have an internet connection for lookups. Force-quit and reopen the app. If the problem continues, send us the exact callsign you tried and your iOS version.
