About Radio432 — 432 Hz Radio
Listen to internet radio from around the world – and keep it in tune. Radio432 first measures how your station is tuned, then retunes it to 432 Hz. Switch it off any time. 1 week free trial, then in-app purchase. Also in the car: Radio432 runs in CarPlay. HOW IT WORKS Radio432 analyses your station's live stream via FFT and measures its real tuning. Only once a measurement exists does the app retune — never blindly, never guessed. The frequency gearbox on the Now Playing screen shows you in real time what's happening: where the pitch comes from and where it's being pulled. 432 Hz instead of 440 Hz is about −31.8 cents, just under a third of a semitone. Whether you want it is up to you: correction can be switched on and off at any time. ON THE ROAD AND AT HOME (in-app purchase) • CarPlay: full control right in the car • Apple TV: big screen, plays in sync with your other devices • iPhone & iPad: station search, favourites, several design themes Pair several devices on the same network – iPhone, iPad, Apple TV – once with a comparison code. After that they play the same source in step (multiroom). TRY FREE, THEN UNLOCK You try Radio432 free for the first week – no subscription and no payment method needed. You start it yourself in the app with the "Try free for 7 days" button. After that you need an in-app purchase: monthly subscription, yearly subscription or a one-time purchase without subscription. All features described here are included. You see the price before you buy, in the app and in the App Store. Subscriptions renew automatically unless you cancel at least 24 hours before the end of the period.
