Acapella Maker - Video Collage

This is my first time using this app, it sucks. It's filled with bugs, if I stay on it long it closes on it's own. There is no option to listen to the 1st video while recording another which sucks, we should be able to listen to the 1st video while recording the 2nd one, and the 1st and 2nd while recording the third and so on. The option of listening to music while recording sucks to me because the sound of the music enters the Acapella, I am supposed to be able to listen without being a part

The app is great but I am unable to use it, the reason is that the previous version though not with this my hot 9 Android,, the previous version has an option for calibration and the option of listening to your first record while recording a second but now it is not available. I paid for a free version thinking all of the stated issue will be provided but it was just the same thing..

There hasn't been an update since 2016! This app started out being really cool but now the synchronizing has been off considerably. When you try to move your picture to another square, the app completely shuts down. I have paid money for this app and I would like for it to be fixed and updated please. I truly enjoy creating songs and harmony from this app. Are you guys even operational? I have sent emails in the past and no one has replied back. No Bueno
