For as much as we ask of our calendars on our phones, they’re really only as smart as we make them. If we forget our friend’s birthday, it’s because we didn’t input it; if we’re late to a meeting, it means we messed up an alert. Tempo Smart Calendar, the first of what is sure to be a new generation of calendar apps, aims to take user error out of the equation. It also integrates with your social schedule like no other calendar. Along with usual iCloud and Google syncing, Tempo scans your email, contacts, and Facebook friends to generate a complete picture of your life, from tomorrow’s presentation to next month’s ski trip.
