About this app

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."

Ratings and reviews

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.

I was excited that Elf Audio has a bunch of tutorial videos on Youtube, so I got the app and the add-ons excited to learn. I soon realized most of the videos, especially the beginner ones, are 4-5 years old and often don't reflect the current layout and features, so they aren't very useful. It looks like a cool app that people who know how to use it can do great things with.

Just stumbled on this app a couple weeks ago. Gotta say, it's the best sampler for android you'll ever find! I paid for the full version and paid for all the added features and if they release more features.....I'll be paying for those too! It's so intuitive I didn't even need a manual. It's so close to replacing my my entire DAW. Endless possibilities. Easy workflow. I can't get over how incredible it is. I've been creating source sounds on my PC and importing them to the app. 10X stars!!!!
