Latency is a killer. The whole point is the use headphones and record a track while listening to a track, but there is a delay. sync setup does not work. turning app on and off doesn't work. turning headphones on and off does not work. everyone must be lieing, this app is a waste of money. I want my money back!

Have you tried with wired headphones? Because Bluetooth headphones cause large and unstable latency. If that doesn't fix it, contact me at jaytronix@gmail.com. Thanks.

Still love the app. Been using this app a long time, and still have problems with latency, and syncing. But have recently found out its because i have an out dated device. The developer is TREMENDOUSLY helpful, and has been bending over backwards and sideways trying to help me figure out a workaround. Good guy. I will most definitely reinstall this when I get a new device. And would highly recommend anyone who wants a good 4track recorder on their phone to do the same!

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.
