There is no information on whether this app supports the new ipod touch 4g. Can anyone here confirm/deny it's usability? App info is currently processing and/or the app is not yet fully available for sale on the US App Store. (And for the mods I know this is the wrong section but let's be honest, no one looks at the ios apps section.)
It works on iPhone 4 for sure. It even has retina display and all that. The devs really keep up on it. I've been using it as my main tuner for a long time. You won't regret buying it.
The new ipod has a microphone on the back for video capture but I believe it's tied to the camera. If you have the headphones with the mic and controls (I don't believe they come with the device) it should work with that if the app is compatible with any of the older ipod touch models
