It's secure, but after every single opening, downloading, viewing of photo or video, or switching from video folder to photo folder or vice versa, an ad pops up. Every single time, which is excessive. Maybe once every ten actions I could see, but every single time? That's too much. I'm spending more time shutting down ads than I am working with my material.

I just downloaded it today, and compared to the one i used in the past, this one is pretty on par! It hides my photos securely, is password protected, and has an app lock feature that can take a finger print as well as a pin. I'm pretty happy with it so far! I tested just to make sure, and the app also returns my photos to public view intact and undamaged. It has some ads, but the other one did too, and they aren't that distracting. Five stars from me :)

Haven't evaluated yet. Will return with and update.. ok now that I've actually tried it. SMH... It puts an ad up in your face every time you click something. So it starts up.. ad. Menu comes up with folders.. click into folder. Ad with five second wait. Click a file and you get another AD 5 seconds. Click out of the file ad. Out of the folder ad. Settings ad. Every click is an Ad!! So buy the app if you want it enough. Free mode will not be a good option. However when you do buy this app.. it will be very good I think. It runs fast if it weren't for the ads.
