Then Google's calendar app is already installed and tied to your Google account (if you set up the phone that way.) It will also keep your To Do list for you. Contacts should be installed by default and will sync all your locally added contacts back to Google. Calendar will let you add contacts to meetings. Add Drive and install the Google Docs app for on the go editing of documents and stuff. You can also, now, point your phone at physical documents and have the camera scan them and upload them to Drive where Google will try to convert them into editable documents via OCR. It works some of the time. Switch on Google Now and Google will look at your calendar and remind you about appointments and how long you have to get to them. insomniasexx likes this. It terrifies me.
