In Atrix 2 stock China JellyBean, if we install Motorola launcher with circles widget and try to replace the Clock and Timer app with some other one, the circle widget stops responding and will not show the current status of alarms etc. This clock is made for users bored of the same clock app on Jellybean and want a clock with better UI.
This clock app is not my work. This was extracted from HoloBlur ROM of Atrix HD. link
To install, remove the Moto Desk clock.apk and odex (if any) and replace with this clock in /system/app. Set permissions and clean Dalvik Cache and reboot.
