1.) Setting a default method of capture (voice, text, or image), so that when the app is launched, it launches directly into that mode. No need to launch the app and then select the mode. I especially like this because I use voice more than anything else. I just launch the app and its already recording. No need to hit another button.
2.) Use of 3D touch to launch into the capture mode of your choice as well as to select which email address you want to send your info to.
3.) Using the "share" function in other apps, you can capture stuff via Braintoss
4.)OCR for the scanning function
5.)Apparently, there is more cool stuff for the watch version, but I'm not an Apple Watch user so can't speak to that.
