5. Note Vault
In the earlier version of the iOS we had our notes and we had the security measures for certain apps and folders. However, the security could not be implemented in the notes section, thereby leaving all your important notes and data vulnerable to others. The iOS 9.3 will now enable you to put a lock on the notes and you can sort them out by date or name. Now, this isn’t exactly a revolutionary thing but its sure is new for Apple users.
