Metronomes, love them or hate them, they still are very useful for practicing. I have tested a metronome today called Metronome Q, available for the iOS devices. It is a metronome that aims to bring out the little child inside of you by giving you a game-like experience. It is available at the Apple App Store.
It designed with kids in mind - comes with an adorable elephant, which is blowing around hearts from its trunk, and is flying around with the help of balloons. How cute!
I like it. It is great for kids of course, since it is so cute, but it does have some very nice features. If you are bothered by a cute interface such as this, then this metronome isn't for you. I don't mind though, music is for all ages!
Some great features in particular:
Check out this metronome at Greamer.com and you can find it in the App Store.
My daughter is taking piano lessons, and this is a perfect practice helper for her.
