Pocket Informant
“Pocket Informant is a fully redesigned from the ground up calendaring and GTD®-based tasks solution for the iPhone/iPod Touch. Our purpose is to integrate best-of-class calendaring with best-of-class tasks together into one great solution. Version 1.20 makes major improvements in almost every area of the application and we know that we are far from done. Version 1.21 is now available and contains French/German Localizations, many new grouping modes (including Context/Project), redesigned search, Tags, Outlook Sync, and many bug fixes.”
I use this application for my school Google Calendar as well as the todo lists that I create using the online service “Toodledo”. I feel that the calendar features are much better than the calendar app that comes with the iPhone. There is a lot of room for customization and there is a free version that you can try out.
