Earlier this year Ubuntu has unveiled its Ubuntu Touch OS for smartphones. Its first release was made in February. This OS comes with lots of customization options like new animated lock screen which shows notifications for Apps too.
If you like that lock screen then you can get similar one on your Android phone for free. Ubuntu Touch Lock Screen is a very simple and minimal which shows apps notifications in a circle with animations.
You can tweak with setting and change colors, animations, run lock screen in full screen mode. Once lock screen is enabled you can swipe it to left to unlock it, you can also set password for it.
This app is in beta stage but we had used it and we hadn’t faced any issue and it work fine to use.
