App Cloner
After enabling App Cloner, a copy of a particular app will be generated on the Home
screen. The original app and its copy could run simultaneously without affecting
each other.
Clone Apps works only if both the app itself and the phone supports it. If a cloned
app does not work properly, it means that the function or operation is not supported
by the app or phone.
Clone Apps currently do not support data transferring between a cloned app and a
computer. At most two app clones can be operated simultaneously.
Apps That Can be Cloned:
 BBM
 WhatsApp Messenger
