Essential app! When my phone is connected to my pebble i don't have to enter my password. It sounds simple but it's just how I want it. The android trusted device password bypass does not work as well, you still have to swipe the lock screen which annoys me more than I could even begin to describe. I hope this can be ported to nougat or I will be tearing my hair out.
Have had the paid version of this app installed for over 2 years on my Note 4. Have had issues with it randomly not working when plugged in to power for those whole 2+ years and recently it won't even start up after a reboot. It takes more than an hour for it to start working if it ever does. Eventually, for whatever reason, it starts working. Pretty unreliable operation and looking for other options now.
The app has a good premise but is still far professional now. App fails 6 out of ten times while on WiFi letting phone lock. While driving using blue tooth app fails allowing phone to lock. App will not uninstall until many steps are performed.
Been using this since Android L and still working on Android M. Delayed Lock's timer has not failed me yet and I find it more reliable than using Smart Lock of Android i.e., on body detection and location lock. Delayed Lock's lock after disconnected to WiFi or Bluetooth device is a real plus.
Updated Review: This is one of the first Apps I always install on a new device. Sadly Google broke it with lollipop. But It seems to work fine on Marshmallow (Android 6.0) on MotoG Rev2. This is great since I really disliked the experience of using Android without Delayed Lock.
Works flawlessly on Samsung Tab E with Marshmallow! Much better than the smart-lock feature, which still seems to lock the tablet at least once every 24 hrs. Many more fatures than smart lock too. Much better than the SkipLock app I was using on my last tablet with Android 4.4.4. The shortcuts are useful too. A very impessive app and impessively secure when using 'protect settings.' Kudos to developer for a great app with a perfectly reasonable try-out period and a price that is more than fair for such a feature-rich and functional app.
