Memoria Photo Gallery

The default gallery app in Android is already pretty good, and any other application that wants to provide users with an alternative will have to do much better. Memoria Photo Gallery might just be good enough to become a viable alternative.
 
Besides all the basic feature that you would find in a gallery app, Memoria Photo Gallery comes with a few extra ones that should make a difference. For example, users can secure their apps in an encrypted vault, and they can hide certain albums. They can change the album visibility and even choose one to make it sticky.
 
Furthermore, it’s also possible to change the cover photo, to set up slideshows, and even to cast the images to Chromecast.
