I have modified cLock app from CM 10.1 to be installed on non cyanogenmod ROMs.
The source is available at https://github.com/mammenj/android_p...apps_LockClock
I have tested on N4 stock ROM only, so if you find any issues please post which ROM, its version and the device details in this thread only.
App requires JB 4.2.x
Thanks to CM team and @dvtonder (original author)
unpublished from Google play store as dev @dvtonder is not very open to it :thumbdown:
