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 tracks 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 progress instant, keeping you in the flow and keeping it fun, not getting bogged down by pages of parameters and micro-editing.
"Been putting that $4 koala sampler to good use lately. Undeniably great tool that puts some of these expensive beat boxes to shame. A must cop." -- flying lotus, twitter

Desperately needs an arranger feature. It's very easy and intuitive to edit samples and turn them into sequences, but without an arranger there's nothing you can do with them. The sequences just exist individually, like raw ingredients that can't be turned into a meal. It's a baffling omission by an obviously talented team of developers. Koala would easily be a 5-star app, but without this simple but essential feature it's a 3.

I was in need of a fancy metronome for playing flamenco and koala sampler (with the samurai addon) is the solution 😁. I can choose 12 beats per bar, set a 'chance' value for unlimited playback variations, and set the velocity for accents. Just import some free cajon and palmas samples and eat your heart out. The interface is very easy to get around. No tiny menus or buttons. Some things are difficult to find, so I recommend to really watch all the tutorials.

This is quite literally the best music app. If you wanted to make music and can only have one app this is all you need. It's a SAMPLER! You have a mixer, resampling, FX, piano 🎹 roll,Sequencer, time stretch, midi. like d**n😆 it's like you have a SP-404 in your pocker. paired with YouTube to mp3 you can get your ideas out and make all the music you want.
