Obscura stores your private images safely.
Pictures are encrypted with the same master key and password as OI Safe. The picture safe is based on Android's Gallery.
REQUIRES OI SAFE 1.1.1!
This trial version is limited to 10 encrypted images. You can upgrade to the full version by buying a license.
good but a little complex — I do like this app, especially because it encrypts pictures and doesn't just hid them, but it is more complex than comparable apps.
