Koala is the ultimate pocket-sized sampler. Record anything with your phone's mic or load your own sounds. Use Koala to create beats with those samples, add effects and create a track! Koala's super intuitive interface helps you make a track in a flash - there is no brake pedal. You can also resample the output of the app back into the input, through the effects, so the sonic possibilities are endless. Koala's design focuses totally on making the music-making process instant, keeping you in the flow and keeping it fun, not getting bogged down by pages of parameters and micro-editing.
