Its okay to have something in place. The free version has way too many ads, and sometimes, they take over your screen completely. For messages, if you enter your PIN, then add a photo. It counts that as you leaving the app and runs ads again. Even though I'm still drafting the message but adding a picture. It does the job but would not recommend it unless you want to pay the annual fee.

They claim after you purchase a subscription The ads will stop. when I try to put this application on any device the ads come back. They need to be removed by Google. Be wary with this this company. Do not purchase! The ads will continue. If they can't be trusted in the playstore I can only imagine what they are doing with our info. I can't understand how they have so many positive reviews after lying to their customers. The ads aren't being removed if you subscribe. Do not install!

I tried to use this app to maintain some privacy but it turned out to be extremely annoying and slightly invasive. It locked every single one of my apps, including the ones that I didn't select and showed me ads every time, not just when I opened Applock pro even when I entered my password. If I could give less stars I would. Even when I went to delete the app it made me watch 3 ads and enter my password.
