Apple Continuity allows a user to send contact information, presentations, and documents to other iOS users instantly and without network setup or to take a picture or video with your iPad and share it effortlessly across all associated devices.

An Apple Continuity feature called �handoff� allows users to copy text from a document from one device and paste it into an email on a completely different device. It also allows the user to receive a phone call on their iPhone and answer it with their MacBook Pro or Apple Watch.

Continuity can result in multiple potential sources of evidence. If you can�t get into one device, is there a possibility you might be able to get the evidence you�re looking for from another? Also, it's important to realize that just because data exists on a particular device, it doesn�t mean the user was necessarily ON that device at the time the data was created.
