Yes it is true the concept of this app is good. I use this app for a long time and take a good advantage of dual apps but the main point is that the Parallel space hangs your phone every time.
The app is too heavy when you launch this app it takes so much time to open. And phone doesn’t work smother when parallel space runs in background.
Even shortcuts of your dual apps takes so much time having too many ads and do not work properly in day to day use.
So a nice concept is going waste because of app bugs and lags.
Over all performance of this is disappointing to me.
