About

HamsterDB is the ultimate private database for amateur radio operators on iPhone. Keep track of every Ham Radio station you’ve worked and every contact you’ve made — all stored securely on your device with zero data sharing. Add a new station and HamsterDB instantly queries HamCall.net to auto-fill the operator’s name, location, and license class. Need the email address that HamCall doesn’t provide? Simply look it up on QRZ.com, copy the details, and paste into the QRZ field — HamsterDB intelligently maps everything into the right places. Once your stations are in the database you can view them instantly sorted by Call Sign, Name, or Date Created, in ascending or descending order. Export the entire database to a clean JSON file for backup or sharing with other hams. Import works just as easily, so clubs and friends can exchange logs in seconds. All data lives locally in SwiftData on your iPhone. There are no accounts, no cloud sync, no analytics, and no third-party data collection — your logbook stays completely private. Key Features • Automatic HamCall.net callsign lookup • QRZ.com paste-in support (captures email & extra fields) • Sort & filter by Call Sign, Name, or creation date • Ascending / descending order control • Full JSON export & import for easy sharing • Built-in comprehensive help system (CTHelp) • Beautiful, intuitive iPhone-native interface • Works offline after initial lookups Whether you chase DX, contest, ragchew, or just like keeping an accurate station log, HamsterDB turns your iPhone into a powerful, portable, private Ham Radio database. Privacy is built in from the ground up — your contacts and station data never leave your device. Download HamsterDB today and take control of your amateur radio logbook.
