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."

This is easy to use on a phone vs the other apps, very simple to make and save ideas. SO easy to make beats or songs from any sound you wish by recording it or downloading your own samples (some are included to get you started) i generally use Metal drums and guitar samples for ideas.. but also i recorded a sample from my PHONE of my buddies wood burner door screeching because it sounded funny and made a simple but good sounding beat.. 5 stars

The Team at elf are just incredible! So rare that you would get support within the hour on a Sunday night !!! ❤️ i support this App ! I've been using it for a long time 3+ years . Made custom performances using My cello and the akai mini mk2 triggering sections and importing loops from my looper , adding layers of complexity and having a blast jamming and creating with friends. 👌🔥

one of the best bang for your buck, mobile prodcution suites I've used . After spending a total of about 1300 rupees in total to unlock all the features i have, so far (samurai mode and mixer) this has become pretty much my go to sampling daw. everything about it is so damn easy to use.
