Great fun, especially for younger children. My 18 month old grandson loves playing with the bubbles and the fireworks. Its a good way to distract him while his 4 year old sister has a quick game with her granddad.
Everyone I show this app to are really mesmerized by it. My two year-old granddaughter loves the movement and music it makes when she runs her fingers over the screen. I have shown it to a couple of elderly friends and they thought it was wonderful the way it worked, I think the gentleman was quite reluctant to walk away from it. So I recommend this app for all ages.
