Great. Game!!!! ,

The Best I’ve seen on IOS so far!

First of all I’d like to say I hope you [The Developer] never sell out like some of these other music apps have. I can tell a lot of thought was put into making this App and I sincerely hope you continue to be successful and genuine on you’re journey!

As far as the app itself I’d say it’s quite literally what I’ve been looking for all day. I’ve bounced back from app to app, even GarageBand and I gotta say this app is well worth it and I highly favor it now over the last couple things i’ve downloaded.

The premium price is well worth what your getting and it even comes in parts. So your not paying for more than what you need. I’m happy to find there is no subscription. And there isn’t a million add-ons I need to buy every time I want ONE more single feature. It’s fair and well worth what your paying.

I’m able to take files straight out of my iPhone, throw it into the app on some Pads, chop it up and create patterns straight off my phone with ease! Among a plethora of other things I haven’t even discovered yet.

I really just wanted something I could use while on the go when I’m out’n about feeling inspired. All I got left to say is this app among an overly saturated App Store full of glitchy, uninspired, greedy Music Production apps is amazing and well worth the cost.

Trust if you continue down this path of being altruistic and offering quality along side reliability I will continue to support you!

i love this app. 10 stars.

OLD VERSION: but lately after this new update even with NOTHING else playing on my ipad, everything is closed, background app refresh off, etc. It keeps randomly crashing on me and i lose all this work i had done. It is very very frustrating. not even beatmaker 3 or nanostudio do that. and Koala has never done it before. so If the amazing devs could figure this out for me then ill IMMEDIATLY GIVE 5 STARS. i only did one to get your attention. i use this app daily and i rely on it for a side income involving music production! please help!!

UPDATE: thank you so much for the extremely fast customer support. you sir are amazing!! i havent even had time to test the new update, but because the amazing dev got in touch with me so fast and worked so hard to try to fix it, i know that if i have any issues i can just email him directly and he will help me!! thank you so much

Developer Response ,

Hi pr4y, I’m really sorry this is happening to you. Since first reading your review, I have done everything within my means to make koala as stable as possible, and I have made an update for you specifically, I really really don’t want you to be frustrated or have a bad experience with koala. Again, I’m extremely sorry. Please update and let me know if it fixes your problems. (I can be contacted at https://www.elf-audio.com/contact.php)

UPDATE: I have now made a lot of stability enhancements to koala, if you get a chance can you let me know if it's working for you? All the best, and sorry again.

Like a better, more fun PO-33 or SP-404

This is far and away my favorite music app for iOS. I always keep coming back to it, paying for the Samurai update was a no-brainer. If you've ever used a teenage engineering PO-33 or a Roland SP-404 the workflow is very similar. That being said the speed with which you can do things in this app and the amount you can do blows me away. You can just use it as a sequenced sample player or, with the samurai update, you can now start turning your samples into proper synths in their own right (set em to loop and shorten the length a lot). The developer has done a really amazing job of keeping a good balance between quick music creation in the moment, while also providing enough detailed and smart additional tools so that you can tweak your sounds and beats to your heart's content - all without cluttering up the UI. This is one of the few iOS music apps I would actually trust live.

The latest version of koala now lets you play chromatically via midi. Enjoy!!
