Used for years and years. Most of the low scores here are user error. People get frustrated learning a new app's functionality, and rather than use a process of elimination and testing effects, they immediately get mad at the dev and lower the score. This app is one that I put on every new device. It's always been the same (or better) with no ads or cost to the user. This kind of APK gold doesn't come along every day. With zero musical talent, I have created a track that got local radio play.

Absolutely perfect!! As a singer-songwriter you couldn't ask for more. It operates flawlessly on my phone and my Chromebook. No, I wouldn't use it to record a professional band, etc ... But for my purposes, it is absolutely everything I need and nothing I don't. Have not had any glitches or latency issues. It has a built-in latency test tool even. I do have a high-end phone and perhaps that may be the problem with people's complaints. How can you beat this app? I love it.

Great app but it has it's issues. I'll spend a good amount of time recording on several tracks, get the levels where I want them so that everything is sounding balanced, but then as soon as I mix them, some of the tracks I can barely hear and others are way too loud. Even though moments before it was perfect. Sometimes mixing works fine though. Very weird. Other than that it's a great app, just remember to save individual tracks before mixing if you don't want to have to redo them.
