It’s good but let’s say you have an app that works. Then you upgrade and there are so many glitches you just wanna jump out a window. Now - let’s say you have the version of the app before it was broken on another device. Backing up that app via iMazing and trying to transfer that to your device that you want it on unfortunately just makes it download the most recent version, so that doesn’t work as advertised. Just FYI.

Edit - this is just my experience - if it does work I haven’t been able to figure out how which doesn’t necessarily mean it’s the program - may be user error on my part 🤷🏻‍♂️🙏🏻
