I've used this app for years if not for up to a decade! It's been nothing short of excellent in locking my apps & especially gallery (pics & vids). Highly recommended, a little drawback is the ads tho which can be a little hectic and sometimes unskipable requiring you to exit & reopen. Although it's a fair price to pay for it's performance and being free to use

I love this app!!! I've never seen an ad on it and I've had it a significant amount of time. Also, no problems with unlocking between apps, although it likes to slam Google Play shut quickly if the install (an app) button is visible on the screen. As long as I scroll down immediately after opening a page it will remain "propped" open for me.

Spyware/data harvesting app hoping to trick less savvy users with its blatant lies, looking for accessibility special access and device admin permissions (extreme access to device controls and data) that it shouldn’t need. Probably wants to spy on you or sell your data to advertising companies. An obviously malicious app.
