"[F-Stop Media Gallery is] probably my overall favorite app of 2013." - Editor at Android Central

“We Recommend: F-Stop – An Enhanced Media Gallery” — Androidpipe.com
Never again wonder where your photos or videos are located as you search endlessly for that picture you know you took the other day. Let F-Stop manage all your media with powerful features like tags, ratings, albums, and favorites.
Use the smart album feature to automatically create albums based on criteria you choose. For example, you can create an album that automatically shows all your GIFs or only displays media you tag with “Family”. Maybe you are a professional photographer (many professionals use F-Stop) and want to show a client some pictures you took for them. Set up a smart album to show all media with the client’s name as a tag. Add a condition to only show 4 and 5 star rated images so they only see your best. The client can then easily press the heart icon to favorite the images they like. With the PRO version, you can then save these tags and ratings to the file and view them in just about any photo organizer such as Google Picasa, Adobe Lightroom, Apple Aperture, Adobe Elements, etc. The possibilities are endless.
