APRSpot puts your station on the APRS map. Beacon your position to the worldwide APRS-IS network — you'll show up on aprs.fi and in every other APRS client — and watch the stations around you move in real time, right from your iPhone. FEATURES • Smart, periodic, or one-tap position beacons • Background beaconing — drive with the screen off and keep showing on the map • Live map of nearby stations with native APRS symbols • Station list sorted by distance, with speed, course and last-heard • APRS text messaging with delivery acknowledgements • Dynamic Island & Lock Screen Live Activity for your beaconing session • Activity log of raw APRS-IS traffic • Privacy controls: position ambiguity, optional course/speed and altitude • Block and report stations • Free — no ads, no account, no tracking TRY IT WITHOUT A LICENCE Tap "Try the demo" on the welcome screen to explore the whole app with simulated stations and messages — no callsign or network required. FOR LICENSED OPERATORS APRS is amateur radio. Transmitting your position requires a valid amateur-radio callsign (APRSpot does not fill in your APRS-IS passcode automatically, you will need to enter it manually in the Settings section). APRSpot uses background location to beacon your position to the APRS-IS amateur-radio network while you travel, even with the screen off. APRSpot is internet-only (APRS-IS) — no radio or TNC hardware required. 73!
