I am using applock for many years and was really happy with the app performance. But after updating the app recently, my experience is terrible. After closing a locked app, the applock starts with a series of ads and does not stop for close to 30 secs. I am sure there is a lot of revenue for the developer in ads, but you must think about the user as well. I think i will now move to another app where i may have a better expereince.

Do not trust that this will lock your apps I downloaded this app before giving my phone to a service centre for battery replacement. Considering that this app would keep the apps on the phone locked and safe, it turned out to be a total waste. 9 out of 10 times it won't lock your apps to prevent misuse. I tried multiple times to check, but it didn't despite enabling locking after a screen lock. So if you're looking to secure the apps and data from uncalled usage, look somewhere else.

The company even does not deserve to be rated, i wrote them after i developed some issue in my applock old version. The photos and videos were deleted but showing thumbnails, it was displaying only number of images and videos in each folder. Later on i wrote to them and they did not respond. After installing 2021 version it displayed your videos and photos will automatically synchronized but nothing happened and i lost my images and videos. Most disgusting. The company plays with the emotions.
