1 amazingly crafted MouthOff™ app

If you like MouthOff™ you should download Ben 10 MouthOff™ or Ben 10 Alien Force MouthOff™ both available on iTunes.


MouthOff™ is for use on iPhone. It also works with 2nd generation iPod Touch but you MUST have headphones that have a built in microphone. MouthOff™ DOES NOT WORK AT ALL WITH 1ST GENERATION iPOD TOUCH!

Fix for app not working

My son loved this app and he was quite frustrated when all of a sudden the mouths quit moving. To fix this issue I found that you need to turn the microphone permission on for mouth off.

Go to: Settings > Privacy > Microphone and turn on the access for MouthOff

Too Funny

MouthOff is great fun. It's a sight gag that makes children and adults laugh out loud. The kids want to try it and the adults want to know where to get it. Worth 99 cents for sure. You'll get more enjoyment than that from this app.
