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."

Great sampler, but add on cost creep ( you need to buy the two add-ons to get the best from it). but they should be charged and included up front like FL Studio. Really well executed software though and definitely worth the ~£11. Im not sure I would pay more if the price went up further. It would be nice if you could play head scan forwards on long samples within the sequencer and have it still play, also would be nice to lock sequence channels to avoid accidental moving on small phones.

Incredible app. The amount you can do for the amount you pay is insane. There are a few bugs: it freezes sometimes when you import audio, when I leave the app in the background and receive a phone call I have to close the app otherwise the person cannot hear me in the phone call, some glitches after importing large audio files. However all in all, it is a great app and you can do so much. Creating full songs on the go is very powerful.

Blown away! The developers behind this tool really care about music makers to the point of reading their mind 🤯. everything is intuitive and easy to find, for the beginner it's easy to pick up too (my 11 year old lad has been making music instantly with it) it isn't just a sampler, it's pretty much a DAW at this point able to make fully produced tracks to export. the app allows you to use media outside of the app by importing audio and even video (audio rip) it's awesome ⭐⭐⭐⭐⭐

What’s new

- Automation for bus effects and mixer channels
- New "Same pad mapping for all banks" option in MIDI settings - map the 16 pads once and the selected bank decides which pads your notes play.
- MIDI map mode can now be toggled from the QWERTY keyboard (default key `;`) or from a mapped MIDI control
- Looper recording (swipe down on a pad) now starts and stops cleanly on the bar line, including when you stop just after the bar
