Momento makes your photo album more interesting. It stitches related photo (outtakes) and turns them into awesome GIFs. You just browse through Momento and see what cool memories Momento created based on your photo album (automatically)

I'm a little bit biased here 😀 but it's really the easiest tool to create cool gifs because it's automatic!
Justin Garbett- Editor, GIPHY
To add to Niv's suggestion, GIPHY has another web tool called GIF Editor that lets you add stickers and captions: https://giphy.com/create/gifeditorZoomyy for iOS adds a zoom motion to your existing photos/videos. Filmmakers have been adding this motion to clips manually for years, called the ken burns effect. You don't need FCPX, Premier or After Effects to add the motion to your clips on the fly, use Zoomyy!
