Screens
Straight from the phone
Captured on a Pixel 8 running version 1.2. Swipe through the main tabs and a few of the tools.
Spectrum, waterfall, slice tabs and a knob with haptic detents. Band, mode, filter, DSP, TX and PTT one tap down.
Mode, a live filter scope, tune step, AGC — and NR+ beside the radio's NR, NB, ANF and WNB.
Live PWR, SWR, ALC and mic meters, RF and tune power, mic source, VOX, PROC, ATU and a hold-to-talk PTT.
Digital modes, operating aids, activities and station panels on one grid. Long-press to pin.
Activators on the air right now, filtered by band and mode. Tap one and the radio is on frequency.
Callsign and report; frequency and mode come from the radio. Search, ADIF import and export.
LAN radios appear on their own, SmartLink reaches the shack from anywhere, Demo mode needs no radio.
Opus 48 kHz, latency target, Bluetooth routing, phone-mic PTT and bandwidth presets for cellular.
Features
A whole shack. One app.
Receive, transmit, decode and log from one screen. Pin the tools you use most; per-profile workspaces bring them back the way you left them.
Live panadapter & waterfall
Real-time spectrum rendered from the radio's own FFT stream. Pinch to zoom, scroll the band, watch signals bloom in the waterfall. Cluster and POTA spots are drawn right on the display.
Point-to-listen tuning
Tap or drag a signal and the filter passband lands on it — not just the carrier. A tuning knob with haptic detents, with filter width and tune step one tap away.
Transmit from your phone
Hold PTT and the phone's microphone goes straight to the radio. Live power and SWR, ATU, VOX, processor and mic source — on a hold-to-talk button you can't hit by accident.
SmartLink remote access
Operate from anywhere. Log in with your FlexRadio account and connect over the internet — NAT traversal handled for you. Radios on your LAN appear instantly, and it shares the radio politely with your other multiFlex clients.
Opus audio, any network
48 kHz Opus receive audio decoded in hardware, Bluetooth routing, and latency and bandwidth presets for cellular and hotel Wi-Fi. A foreground service keeps it alive when the screen locks.
DSP with NR+
On-device NR+ neural noise reduction alongside the radio's NR, NB, ANF and WNB — tap to toggle, drag to set level. Live filter scope, 8-band RX and TX EQ, notch filters and split.
Digital modes built in
FT8/FT4, RTTY, PSK, CW, SSTV, HF-Fax and WSPR decoders, with RTTY, SSTV and CW transmit, on-screen iambic paddles and CWX. Callsign lookup cards on every decoder.
Spots & POTA, tap to tune
Live park activators and cluster spots filtered by band and mode. One tap puts the radio on frequency in the right mode. Net reminders alert you and tune on tap.
Logbook & shack tools
Log with frequency and mode straight from the radio, ADIF import and export, QRZ lookups. Memories, band stack, voice macros, a QSO recorder, and panels for PGXL, TGXL and rotator.

FAQ
Frequently asked
Which radios does it work with?
Any FlexRadio that runs SmartSDR: the FLEX-6000 series, the FLEX-8000 series and the Aurora series. Developed and tested against a FLEX-6400 running SmartSDR v4. Anywhere on your LAN, or remote over SmartLink.
Can I transmit?
Yes. Phone-mic PTT streams your voice to the radio, voice macros key up from your phone, and RTTY, SSTV and CW transmit from the built-in tools. Mic PTT currently sends uncompressed audio, so it works best on your LAN; compressed transmit audio for cellular is in the works and will be a free update.
Can I try it without my radio?
Demo mode runs the whole interface against a simulated radio, so you can learn the layout from the couch. A first-run tour walks you through the Radio screen and can be replayed from Settings.
Is there a subscription?
No. One purchase on Google Play, yours forever, every update included. No account with us, no ads, and nothing sold. Optional anonymous crash reports can be switched off in Settings.
Is this an official FlexRadio product?
No — it's an independent, third-party client built by a ham, for hams. It's not affiliated with or endorsed by FlexRadio Systems.
Where do I get help?
Join the Discord to ask questions, report bugs and request features, or email the developer directly. Both links are in the footer and in the app under Settings → About.
