5NN Mobile is the field companion for amateur radio operators who run and join severe-weather and emergency communication nets. Built by operators who couldn't find a single tool that did it all, 5NN puts net check-ins, live operator mapping, structured weather reports, and weather alerts in one app you carry into the field.
Pair it with the 5NN Control web console used by net control, and your whole team — from the controller at the desk to spotters on the road — stays on the same page in real time.
WHO IT'S FOR
Licensed amateur radio operators participating in weather nets, storm-spotter activations, training nets, and emergency communication exercises.
KEY FEATURES
• FCC-verified accounts — sign up with your callsign, validated against the public FCC ULS license database. No callsign, no fake accounts.
• Join a net in seconds — enter a club's callsign or pick from live nets nearby, then tag every check-in and report to that activation.
• One-tap check-ins — set your status as Stationary, Mobile, Emergency, or Off-duty so net control always knows where you stand.
• Live operator map — see everyone sharing location on your net, color-coded by status, with callsign labels, recent reports, and one-tap navigation to any operator. Choose Standard, Satellite, Terrain, Dark, or Voyager basemaps.
• Live location tracking — opt-in, off by default. When you're checked into a net, share your continuous position so net control can see you move on their map. Update rate adapts to your status, and the iOS background-location indicator makes it clear whenever tracking is active.
• Structured weather reports — file NWS-style reports for tornado, funnel cloud, wall cloud, hail, damaging wind, flash flood, heavy rain, snow/ice, lightning, and more. Add magnitude, mark it measured or estimated, attach GPS coordinates and a photo.
• Weather alerts — stay aware of active alerts relevant to your net.
• My Reports — review everything you've filed, newest first, with photos and locations.
• ICS-style activity log & roster — follow the net's roster, log, and reports right from your phone.
PRIVACY & CONTROL
Live tracking is opt-in and only shares your position with the active net while you're checked in. Turn it off any time from your profile, by going off-duty, or in your device settings. We don't sell your data or use it for advertising. See our privacy policy at https://5nn.app/privacy.
IMPORTANT SAFETY NOTE
5NN supports amateur-radio nets and is not a 911 system or a substitute for official National Weather Service warnings. Weather data, radar, and operator positions are for situational awareness only. In a life-threatening emergency, call 911.
