Not worth a buck. Can't change back to white once you pick red or blue. No shapes other than straight line.
To change back to white, just hit the red or blue button again like on off switch. Loved this app.
Not worth the money
Works great! My 3 yr old loves it! Using Samsung fascinate.
My daughter loves it
Update: Can now save to SD Card.
Added both Red and Blue sparkler color changer buttons, enjoy.
To change back to white just tap color again.
