Everything you need to
run a band — on a phone.

Live band decoding & waterfall

A continuously scrolling waterfall with UTC timestamps at every FT8 period, tap-to-tune labels, and decodes in milliseconds.

Active QSO monitor

A collapsible panel tracks your current contact through the full auto-sequence, with a caller queue so you stay on target.

USB CAT radio control

Drive your rig directly over USB-C — CAT control, audio, rig models, and DATA-USB bandwidth handled, with auto-connect fixes.

Cloudlog & QRZ logging

Automatic log upload to Cloudlog and QRZ the moment a QSO completes — configured once, then out of your way.

Full English localization

The original was Chinese-only. FT8AF is translated end-to-end, with RTL support and clean, readable menus throughout.

Material 3 dark UI

A complete Jetpack Compose rebuild — fast, legible at a glance in the field, and easy on the eyes during a long night of DX.

73 from the road

Most of FT8AF was vibe-coded on I-70 at 70 mph, heading to and from Hamvention — laptop on the passenger seat, radio in the back, Claude in the loop. Some of the best debugging happens at highway speed.
