Pros
Pro Works as a personal assistant
If Tempo tempo gains access to e-mail, contacts, social networks or any other of the service integrations it supports, it will use that information to automatically fill out the calendar and serve up context based information such as related emails, files and contact info.
Pro Gives directions to an event's location
If location information is listed within calendar, Tempo can show the directions through an inline map.
Additionally, if the address to a desired destination is not listed in the calendar, Tempo can search services like Foursquare to figure out the location. This feature also displays contact info of the destination.
