Amateur radio apps for iOS
Effective: August 5, 2026
QSO is an amateur radio contact logger.
QSO collects nothing. There are no accounts, no analytics, no advertising, and no tracking. Your log syncs only through your own iCloud.
Contacts you log are stored on your device and, if you’re signed into iCloud, in your private CloudKit database — encrypted by Apple and readable only by your devices. We have no server and cannot see your log. Location, if you use it for a grid square, is converted on-device and the coordinate is discarded. Export is always something you initiate.
