I read it had ads, but thought 'How bad could it be?' Well, they are so obtrusive, while you are trying to operate a Hide app, the ads start playing music,and there are Allot of them. Now, they do offer a paid version, and there are two features I love. 1) Fake password. 2) put the phone down, and app closes. I found an app that has more options, it's much easier to unhide, and no ads. I'm going with that one, though if you pay for this, and you want basic, this will work.

Great app, does what it says EXCEPT for a major problem with the applock ( i. e. Don't download for this feature). Great list of features for free in settings that aren't even in description. The only problem is the applock. It shows a passcode to open the app, but if you click on a bouncing picture of a present in the top right of the screen (VERY obvious to click on) you can watch a ad and the app unlocks! I'm not even sure if this is a glitch or something on purpose, but I am not able to use this feature. I have another app now but I'd really like to have this one for that. I've also held off from their "remove ads” payment for this reason all the other features are great and the only reason I'm not giving it five stars is be ause of the applock problem

Does what it's supposed to but be careful I tried the free version for about a week to test it, and it it does exactly what it's supposed to. However, the ads are annoying so I paid to have them removed (please note that I am a cheapskate and very rarely pay for apps or anything app related). The ads have not been removed and I have reached out to the developer and have yet to receive any feedback or resolution.... else this would be an easy 5* rating.
