Security system is very simple. You need to initially set a password. Then go to gallery and select the photos that you want to hide from view, click on the share icon and choose this program. After that, to view these photos you must know the secret code that only you know. In addition, to make it work, all photos must be in the same folder. SUMMARY: Focus - photo sharing allows you to not worry that someone will be able to see that he should not see, and when you try to do it will notify you by sound and vibration.
