Better choices elsewhere...

It might be ok as a Photos extension, but as a stand alone for serious work, forget it. There are far better and more powerful options out there that are just as easy to use as this very stripped down, simple app that is anything but simple to use.
If this app was free you might want to try it but my bet is that you will delete it after a few attempts as it’s simply not worth it when there are superior options out there.
