Super annoying. I have used AppLock for as long as I have owned a smartphone. Unfortunately I won't be using it anymore as I just upgraded to a Samsung Galaxy S23 and the loud video ads that pop every time I unlock an app is simply too much. Seems I had to download a new version of the app and right away the ads started. I lock too many apps, functions, etc. and I'd drive me crazy to have to sit there looking or having to lose every ad every time. It is free but it's not worth it to me.

Hi Jeffrey, Sorry for the inconvenience and thanks for your feedback. However, AppLock only shows silent ads, those ads might not be from AppLock. Could you please send a video to us? We will check the problem. Our email:

Uses a huge amount of backround data, and the ads can be really long and intrusive. Literally every time u push a button it shows an ad. Other that that its a good app for locking apps and photos. As for disguising it as a calculator, I think it would be a good idea to make it a functioning calculator but open the app if u type in a certain code in it though.

I'm finally uninstalling this app. Not sure what happened over the years. It used to be great. The lock timer stopped working. I followed all instructions (device admin, etc.). The lock widget stopped syncing (widget would show locked but app wasn't and vise-versa). I've tried communicating with the developer and no Bueno. I'm throwing in the towel and looking for an alternative. Good luck to those who stick with it. Wish I could give 0 stars. I'm done!
