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."

Ratings and reviews

This app is soooo fun! I've just been sampling all sorts of random sounds and instruments in my house and then playing around with the sequencer mode with the sound. Note really for recording at all yet, but for just applying a small sampled sound to different music scales. The app is really well thought out and has a ton of features. The only thing I don't like about it is that the mic is basically on the whole time, not just when you are using the app, not sure why that would be preferred.

A truly wonderful application inspired by classic hardware samplers. Loading and editing samples is very intuitive and easy, sequencing takes some learning but it also incredibly powerful. While not its full intended function, this is one of the best audio *editors* on Android just for ease of use. So even if you dont want to mess around with beat sampling, creation, its a great tool to have on your phone.

I love this app so much, and I would give it 5 stars if it weren't for this one weird bug that happens intermittently. Sometimes, when I open the app, the audio output just won't work at all regardless of the device I'm using. I've fully upgraded the app because it's just so feature-loaded and I adore the workflow of it, but this bug drives me crazy and completely kills my creative impulse when it happens!
