With the 4th of July just around the corner, I wanted to pass along a super fun FREE app called Fireworks Arcade for both iPhone and Android.
You launch fireworks with the touch of your finger and the cool thing this one has over others I have tried is that you can drag your finger around the screen as well and create quite an impressive show! And it is instantly responsive, no lag at all.
The fireworks themselves explode into different shapes randomly the longer you use it, like stars, smiley faces, hearts, circles, etc. similar to some of the newer fireworks you'll see at a live show.
