There are very few names in the Magic industry that when there name is attached to a product you know it’s going to be incredible. Marc Kerstein is one of those very few names. Earworm is no exception. Highly recommend.

This app works perfectly. A real fooler. It's easy to learn and the support from Mark is great. I recommend this very highly. Five stars for sure. There is even the Facebook group for owners of this app, where you can share ideas with other magicians. How cool is that?

This is a fabulous concept . Works like a charm . I love this app so much , I would easily have paid double or triple the price for this effect . Buy it now , or maybe not I want it all to myself .

This app works as advertise and it has really freaked the people I have performed it for out. And what is even better is Marc, the creator, continues to enhance with user feedback. Love it.

This app does not work. AVOID!

I’m a solo performer so maybe this is different if you have a assistant with you. Keeping it short, now when you try to submit the song their phone won’t automatically go back to YouTube. Apple will ask you “do you wish to open this in YouTube” which ruins the whole thing. You could try to work around it by saying you’re going to “press play for them” but that’s just not as special. I’d like assistance with this if anyone has work around but honestly I think this app now fails because of this.
