I am going back to school and need an advanced task/calendar management system. The market has lots of possibilities, and the stock Google isn't quite going to cut it for the sorting and labeling I want to accomplish. Also: I really want an app that will sync (or has an equivalent model available) with iPad. Syncing via google would be fine, as long as all my info isn't lost in the mix.
-Hour by hour
-Advanced tasking by subject
-alerts per item on both devices
-web access or the ability to modify on my PC would be a plus
I am willing to pay money for this.
