IMPORTANT: RADIOSYNC IS A SIMPLE AUDIO DELAY APP. It does not provide sports radio audio streams. You must connect your own radio tuned to the desired broadcast and your own headphones or speakers through which the delayed audio will be played. This requires additional third-party adapters for your iPhone, iPod, or iPad. Do not purchase this app unless you already have the necessary adapters or are willing to buy them. Refer to our support website for instructions: http://radiosync.dairystatedesigns.com/setup Use your iPhone, iPod, or iPad to synchronize your radio with your TV for live events! DO YOU LOVE your local sports radio announcers so much that you listen to the radio while watching the game on TV? Does it drive you and your loved ones crazy when the radio play-by-play comes seconds before the delayed TV signal? Sports fans rejoice: RadioSync is here! RADIOSYNC ALLOWS YOU to delay a radio broadcast to match a television broadcast. Featuring simple, intuitive controls and a pleasant design, RadioSync gives you the power to synchronize your favorite football, basketball, soccer, baseball, hockey, or any other sports team broadcasts. Although syncing a sports broadcast is the most likely reason to use RadioSync, you can use it to sync any live event that is broadcast on both television and radio. NOTE: RADIOSYNC WILL WORK ONLY when your radio broadcast is ahead of your television broadcast, which is generally true.

Verdict

The call

The clearest difference is price: AltitudePlus+ at Free against RadioSync's $1.99. AltitudePlus+ also leads on rating (4.0 vs 1.5) and update cadence (every 2 weeks vs every 16 months). RadioSync's advantage is in-app purchases (none vs 2) and ads (none vs shown). On chart position there is nothing between them.
