A free program for Android, by Moblynx.
Gallery KK is a simple and intuitive gallery for all your photos and videos, which is not only free, but also for all devices.
Gallery KK can help you sort and organize your photos, videos, and other files, such as albums, folders, or even the app itself. You can also use it as an image viewer, video player, and file browser.
When you install Gallery KK, you will find a new button on the bottom left side of the app that allows you to add tags to your photos and videos. This is very useful because it will help you to organize your files in a better way.
You will also find a new option on the settings menu that allows you to disable the action buttons. These buttons appear on the bottom of the full picture view. If you prefer, you can set them to be disabled.
