User reviews
A synth of great quality for Android. Intuitive, it has a lot of options and is working perfectly.
Night radio is my personal hero. I have bought every app he has on the market. They are all extremely well coded, interesting, and amazingly efficient.
Best 60's spaceship noises EVER
Love it.
Its just enough fun for the right price. Works well in covering up the mating calls of alley cats.
Works great. Fun to play with.
