This is a great app that does exactly what it says it does and does it well. Its not really free if you want to get any worth while use out of it, but the fully unlocked version is worth the $2.99 in my opinion. I like that it has Dot Lock and password lock, its nice to have both options. It also has some really good hidden folder features. I do wish it had the option for the Dot Lock not to show your pattern when unlocking it, most Dot Lock securities have that option these days and its a very useful feature to have. Please add that soon, Devs. All in all its a great app that I actually use and feel secure using. I just hope I never have an issue where it crashes and I lose all my saved content which seems to have happened with many other photo vault/folder apps. Highly recommended
