I use SPB Diary solely for the extended calendar functionality on my Today screen. It gives me the freedom to show the calendar for up to 7 days ahead, and helps me plan my week. As a consultant I attend a lot of meetings and therefor my calendar controls my day and it is important that I have a full calendar view which this application gives me. It’s a must have.
SPB Diary supports Windows Mobile Pocket PC and Smartphone from 2003 and forward.
