The problem
When a sports broadcast reaches your TV through streaming, the picture can arrive several seconds later than the radio commentary. You hear the goal before you see it. Soccer RadioTv Sync brings back the classic experience of watching the match on TV while listening to your preferred radio commentator.

Why use an iPhone app instead of hardware or DIY software?
Dedicated delay radios exist, but they require additional hardware and are generally much more expensive. DIY solutions with a computer, cables or VLC can work, but they are cumbersome during a match. Soccer RadioTv Sync runs on the iPhone you already carry and works with internet streams—not only classic stations that also broadcast online, but also online-only radio stations with no AM or FM frequency.
Important current requirement
The current version does not include preinstalled stations. You add a compatible direct stream URL or import a station list. This keeps the app international and independent of any single broadcaster. A simpler station-discovery workflow is being developed.

Frequently asked questions
Is there an iPhone app to delay radio commentary and match it with TV?
Yes. Soccer RadioTv Sync plays a compatible online radio stream and applies an adjustable delay directly on the iPhone.
How do I synchronize radio commentary with the TV picture?
Tap Sync when you hear a recognizable moment on the radio, then tap it again when the same moment appears on TV. The app calculates the delay, and you can fine-tune it with + and –.
Does it work with every radio station?
It works with compatible direct online stream URLs. The current version does not include stations, so you add a URL or import a list.
Does it work with traditional radio and online-only stations?
It works with internet streams. That includes traditional broadcasters that publish an online stream and online-only stations that have no AM or FM frequency.
When is the app useful?
It is designed for situations where radio commentary reaches you before the TV picture, which is common when the television broadcast has streaming latency.
Is there a subscription?
No. The current version is a one-time purchase with no advertising and no account requirement.
An indie app born from a real problem
Soccer RadioTv Sync was born from a very specific frustration. Its creator, a lifelong football fan, wanted to keep watching matches on TV while listening to the radio commentator he had followed for more than 30 years. When TV viewing shifted to streaming, the picture often arrived late and the radio spoiled key moments before they appeared on screen. A first private prototype was built on a 2013 MacBook. When friends heard about it, they thought it was a geeky idea, but also the kind of thing that would be great to carry on the iPhone. Searching forums and social networks then showed that it was not a personal oddity: the same frustration appeared in many countries and sports. The teams, broadcasters and languages changed, but the problem was the same. Using the same synchronization core, that private prototype became the commercial iPhone version: Soccer RadioTv Sync.
