Originally published September 8, 2020. Updated November 12, 2026 to feature QSO One for internet-linked voice. This revision also adds other apps for the shack and field and refreshes the download links.
QSO One is the featured app for internet-linked voice. The roundup also covers apps for logging, remote listening, CW practice, and APRS.
When you’re setting up at a park or sitting down at the rig, the right phone app can save time finding a repeater, logging a contact, or checking the bands. These ham radio apps for iPhone and Android cover those jobs and show you which tools work with the phone you carry.
Featured app for Android
QSO One
Use one push-to-talk app to reach AllStarLink nodes, EchoLink conferences, DMR talkgroups, D-STAR and System Fusion reflectors, and other supported networks over the internet. Net Finder helps you find scheduled nets, and a built-in logbook keeps track of contacts. Have your callsign and any network credentials ready before you connect. Android and Windows are available. The developer lists iOS as in development. Google Play · Downloads and iOS updates
