Useless unless you have a PC, time, and more programming knowledge than the average user.
If I am redirected to a third party site and need a to download more software to convert files just to use this app, it doesn’t work. Maybe if I had a PC and some time to brush up on my coding skills… but then I would probably just download Stable Diffusion for free and run it on the PC… so… I just deleted half my pictures on my phone to accommodate a file that I can’t convert to a useable format and paid $2 for the inconvenience. Either update the description with requirements, or the app itself, or please just remove it from the App Store because this was a huge waste of my afternoon.
