This is exactly what I was looking for! I'm a musician who wanted a four track recorder to work on ideas but didn't want to deal with major latency issues that I had with another app that I was using. Easy to use and create songs. And, if there is a latency issue that too is easy to correct. Also, has effects. I highly recommend this app well worth it. No need to look around anymore. This is it. Definitely five stars.

This is SO easy and SO useful and you're never going to spend under $4 for such return on investment again! In Windows-land I use Presonus Studio One and Reaper, and am used to complicated settings and the beauty of J4T is how simple and foolproof it is. I wonder out loud to suggest to developer to have the latency check as the first thing that shows up on a new device, because it's incredibly sad to see the recent review where its called junk, yet it's SO easy to set the latency properly. I've had a blast recording acoustic guitar with headphones into my Android phone. The quality has been better than I expected once I bring the files into my computer's DAW. I also beta test for one of the best audio noise reduction suites and thought this would be a lot noisier than it is. But with a headphones, closed ear buds the other tracks won't bleed into the main one. If I find faults they're noting really. The left arrow to get to the settings screen is always close to the fader and screws it up, but that's minor. And like others here I wonder what the metronome could do as well. I love the idea of recording the metronome to one track, because that would make it a LOT easier to sync this once you brought it back to a major DAW to work around. My favorite Android is a $9.99 Best Buy Huawei with no SIM in my area and the microphone CAN sound pretty good! Experiment! In conclusion, this is the best at what it does, and I feel so strongly that this is my first review ever for anything Google :-) I emailed the guy and he's real cool too. Cheers bro!

This app has been one of the most important things in my life for going on 6 years. Using the J4t I have recorded hundreds of songs and about a dozen albums. The in board effects are incredible and making mid fi recordings with great atmosphere is totally possible. I just love this thing. Recently, my phone got stolen and when I got my new one I found a model I liked and signed a contract for it...then when I got home I realized...no headphone jack. Please.. Blue Tooth accessible upgrade soon?xo

Nice to hear the app has been useful. About Bluetooth: it adds a lot of delay, so for recording audio, it's probably best to use wired headphones. Didn't the phone include a 3.5mm-to-Usbc adapter? Bluetooth earbuds should work with the app though. If it doesn't work on your device, please contact me (at jaytronix@gmail.com). Thanks!
