Some people are simply amazing with remembering faces. I'm not one of them. Evernote, creator of the widely-renowned note-taking app of the same name, has set out to help me with Evernote Hello. I guess you guys can use the app too. The app is a visual contact list that puts your contacts' faces front and center. It even allows you to take down notes of how you met someone, and tie notes in your Evernote account to your contacts' encounters.
The app actually takes a pretty unique and, for the digital world, intimate approach to creating contacts. You can add new people the usual way, by importing them from your existing contacts or adding them manually, or you can hand your phone over to the person you want to add.
