Radio Companion
Utilities
$1.99
The companion for your shortwave radio: what's on the air where you are, live band conditions, and a one-tap log of every catch, with a clip if you like. No cables.
Your radio stays exactly as it is. Every session gets better.
Radio Companion sits beside your shortwave radio while you listen. It's made for portables and vintage sets with no cable or Bluetooth. You tune by hand, as always, and the phone shows you what's out there, helps you log what you hear and keeps it for you.
WHAT'S ON NOW, FROM WHERE YOU ARE
See the stations on the air right now, grouped by band with the most open band first, and how well each should reach you. A status card shows the sky where you are, each band's chances this hour and what's starting soon. The broadcast schedules are inside the app, so it works with no connection.
TUNE BY HAND
Type the frequency your radio is on and see who's likely there: the station on the air with its reception estimate, others on the same frequency, what's nearby and what comes on later today. Use the arrows to step through the scheduled frequencies.
CATCH WITH ONE TAP
Heard something? Catch saves the moment, the frequency and who was scheduled there. If you want, it also records a short clip through the phone's microphone. Not sure who it was? Leave it to identify later, or search the whole schedule around that time and frequency.
CONDITIONS YOU CAN READ
See each band's chances hour by hour, estimated for your location and refined with live space-weather data from NOAA: the ionosphere, solar flares and the aurora. When something is happening on the Sun, the app tells you in plain words what it means for listening. A map shows where a band's signals come from, and the path a station's signal takes to reach you, hop by hop.
A LOG THAT'S YOURS
Give each catch a SIO signal report, your receiver and antenna, and a note. Send stations reception reports with your clip, and keep track of the QSL cards that come back. Get a recap of each session, see your firsts, and fill a passport with the countries you've heard. Search and filter the log, correct a catch or add one by hand, and export it as CSV or ADIF.
CALM AND ACCESSIBLE
Designed dark first for a dim room, with a light theme and high contrast. Large text follows your phone's text size, touch targets are big, VoiceOver works throughout and the app is easy to use with one hand. No sounds: a gentle haptic only confirms a catch.
PRIVATE AND OFFLINE
No account, no ads, no tracking. The app collects nothing about you. It never connects to your radio and never transmits: it only receives. Its only network requests fetch NOAA's space-weather data, which you can turn off in Settings, and the app works fully without it.
IN YOUR LANGUAGE
English, Spanish and Portuguese. A short guided tour shows you around the first time you open it.
App updates bring new schedules at each season change, in late March and late October.
Station schedules: EiBi and the Aoki list (NDXC). Space weather: NOAA Space Weather Prediction Center. Radio Companion is not affiliated with them.
