Like all iPhone owners, we love web apps built specifically for iPhone. So we were excited yesterday when the Google Calendar team announced their new iPhone interface (shown here). It's fast, easy to navigate, and unlike iPhone's built-in calendar, shows events from different calendars in different colors.
But Google Calendar's iPhone interface also has some limitations. There's no way to edit events, move them to a different time, or delete them. There are no day or month views. And of course, you can't view your calendars or receive reminders if you're offline. For these things, you'll need to use iPhone's built-in calendar application.
Spanning Sync users enjoy the best of both worlds. They can use Google's iPhone interface to quickly glance at their color-coded schedules online, and use iPhone's calendar to edit events, see day and month views, and get reminders—whether online or not. Together, Spanning Sync and iTunes keep your iPhone, iCal, and Google calendars in sync.
We're excited to see continued innovation from both Apple and Google and are proud to play a part in making those innovations work better together.
