Is there a way to insert the current date in Notes?
[Late Post - posting in case it helps anyone else]

On iPhone (iOS 11+), the "Insert Date Keyboard" provides an easy way to insert the current date in Notes or any other app. If you want to include the current Time in Notes as well, the date format (under advanced settings) would be something like: "yyyy/MM/dd hh:mm"

Note: The app costs a dollar
