Heads up: the Play Store build is on an internal test track

You may need to be added to the tester list before the Google Play link will install. If it won't open, grab the free APK from GitHub in the meantime — it's the same app.

Before you start

What you'll need.

USB-C → rig
OTG adapter for older phones
Radio
CAT-capable HF rig
IC-7300, FT-891 & many more

No rig handy? You can still explore.

FT8AF will decode from the phone's microphone, so you can watch the band and learn the interface before you wire up CAT control. See the FAQ for supported radios and cabling.

Pick your path. Work the world.

Free on GitHub, or $3.50 to keep it updating itself. Either way you get the whole app.
