My friend is engaged,

I used the app you mentioned mainly to clean up old family photos, and it did a solid job, especially with faded colors and scratches. I also turned one of them into a picture frame gift for my mum's birthday—she loved it. The black-and-white enhance feature worked best for me, though some colored ones turned out a bit too bright, so I just adjusted brightness before running the final version.
