F-Stop Gallery Pro

★★★★★ A great gallery app that fully meets my needs. Happy to pay for the Pro version. Multiple ways to organize your catalog and more functional than the standard Gallery app. The learning curve is slightly steep, and you do need to think about how you want to organize your photos and spend a little time learning the app. The developer is very responsive and helpful.

★★★★★ Very good, plenty of advanced features to delve into. Tags and the ability to create albums with "smart rules" has been a big plus and "Open Selected" and the thumbnail panel are fantastic! There are minor UI things I wish were different, like how the bottom bar in the media viewer will float once you toggle the thumbnail panel on and off again, or the lack of search for the many, many settings. I do wish I there were date format options (month name) and a batch flip (like batch rotate)

★★☆☆☆ I'm so confused. All I want is a gallery that has groups with folders in them. Example: group is Animals, folders in the group are Birds, Cats, Dogs, etc. I have no idea how to use this app, and the tutorial is hopeless for people like me who have ADD. Very confusing.

★★☆☆☆ I would like to move a picture to a folder, it loaded an almost 300 folders. Nice app to manage images? Better than the unpaid apps, though slow it's easier to manage files.
