I’m a Gacha editor, and have been for a few years. I decided to test this app to see if it’s any good, it’s okay. A lot of the transitions included seem unnecessary, and it was initially difficult to figure out how to remove them. Overall though the actual capabilities when it comes to using it are fine, but it could be presented better. It would likely be difficult to do things like tweening and animations in this app because of the layout. Another thing I didn’t like is the sheer amount of ads, and I get it, it’s a free app and you need to make money, but it makes it very frustrating to use, almost every time you open or close out of something there is an add. Also, if you have a device that doesn’t run as well it seems subject to crashing.
Personally I would recommend getting a different app for Gacha editing, like Cute Cut, KineMaster, or Alight Motion, they are more complicated, but there are plenty of great tutorials out there.
