Reviews From google play store

I've been using this about 10 days but it doesn't lock all the apps I've selected, sometimes it lets the app open & run for several minutes before it shows the unlock screen, and sometimes it wants me to unlock the app again when I exit the app. looking for a replacement, then will uninstall.

I want to be more constructive and social media, youtube and tumblr are taking precious time of our life. So in the quest to stop myself from lurativeness of internet. I found this app and for some time it was working fine but far.... But after restart it does not seems to be working. And in that time I can delete this app... and start waisting my precious time again on internet. please fix this and I will give u one million star rating.

what I like about this app above pretty much all other applock apps, this app allows you to make very complex and hard to remember patterns or number pins compare the regular 3×3 patterns and/or 4 number pins for others to not guess or you if you want to avoid temptations of distracting apps. yay!!!

Sometimes the lock become deactivate by it's own self. Please fix it as soon as it possible or else my information that is inside app will be viraled. Fix it and I will give you 5 stars.

Pretty cool except I think it would be better if you could make the pattern invisible so others won't be able to see the pattern which was chosen by the user

The app has moments when it doesn't trigger, making the app randomly useless. once fixed rating will be updated.

Everything is great. But notification bar can't be hided. Hence msg can be directly read from notification bar Can you fix it pls ...? If it's done it will be best lock app ever...

Everything is great. But notifications cannot be hide ... Hence msgs can be read directly from notification bar and hence disappointing. Can u fix it pls

Does not have continued locking except occasional activation

view network connections

retrieve running apps
Allows the app to retrieve information about currently and recently running tasks. This may allow the app to discover information about which applications are used on the device.

full network access

prevent phone from sleeping
Allows the app to prevent the phone from going to sleep.

receive data from Internet
