With the standard Photos app, you have one Camera Roll where all the new photos are saved. You may end up with hundreds or even thousands of photos. It is difficult to find the exact one when you want to share with your friends. In addition, if you have any sensitive photos, they are there for anyone to see.
Photos Ultra allows you to create multiple albums with a simple tap on the “+” button. Enter a name and an optional password, that’s it. If an album is associated with a password, it is protected. A lock icon is displayed on the front page instead of the photo thumbnail, and you have to enter the password to enter the album.
