This app actually duplicates the functionality of an app I published years ago, but eventually had to abandon development of. This one actually does a better job than mine though lol
I am currently waiting for their decision about the Call Notes Pro app: " We are currently reviewing the Form and will provide you with an update on your application within three weeks. "
The app is completely useless without this permissions, so I am really scared with this Google Play team steps. They are moving in the wrong direction.

From the description: "You can also enter notes as to when you are on call and even sync your in-app notes with Evernote and OneNote. "
Once my KEYOne gets here I'll try it.
I use Call Notes Pro
Try Call Notes Pro
Call Notes Pro is the closest thing I know of.
