Spanning Sync sales have been discontinued. More info here.
Spanning Sync 3 is the one app that syncs both iCal with Google Calendar and Address Book with Google Contacts. It gives you even better control over how your information syncs, and is now up to 10x faster!

Sync Calendars and Contacts
What if you could combine the speed and elegance of iCal and Address Book on your Mac with the power and simplicity of Google Calendar and Contacts? Now you can.

Spanning Sync keeps your iCal calendars in sync with Google Calendar and Address Book in sync with your Google Contacts, so you get the best of both worlds.

Built for Lion
Spanning Sync 3 is fully compatible with OS X 10.7 Lion and takes advantage of its support for 64-bit processing.

Spanning Sync 3 is also compatible with Snow Leopard and Leopard. Mac OS X 10.4 "Tiger" users should continue to use Spanning Sync v2.1.3.

A Important Note About MobileMe
As of May 5, 2011 Apple has made a change to MobileMe that prevents Spanning Sync—and all other Apple Sync Services clients—from syncing MobileMe calendars. Please read this note for the details.

Full Support for Google Apps
Spanning Sync offers full support for Google Apps. So whether your organization is a one-person company or a 40,000-person university, your enterprise calendars and contacts are seamlessly and securely connected to your Macs.

Stay Organized Across Multiple Macs
If you're lucky enough to have more than one Mac, keeping your data organized can be a challenge. But Spanning Sync makes it simple to organize your calendars and contacts: just sync all of your Macs to the same Google Calendar account.

So whether you're using your Mac Pro at work, your iMac at home, or your MacBook on the go, your calendars and contacts are always up to date. And since Spanning Sync is licensed per-person not per-computer, you can install it on as many Macs as you like without paying more.

iCal Sharing Has Never Been Easier
Need to set up a shared iCal calendar for your group? Spanning Sync makes it easy. Just create and share a Google Calendar, then sync it with iCal on your Mac. Changes made in Google Calendar show up in iCal—and changes made in iCal show up in Google Calendar.

The Best Way to Connect Google Apps to iPhone
Syncing your Google calendars and contacts with your iPhone is a breeze. Just use Spanning Sync to sync Google with your Mac and iTunes to sync your Mac with your iPhone. Since Spanning Sync takes full advantage of Mac OS X Sync Services, it all just works.

International Support
More than 100,000 people in 58 countries1 have used Spanning Sync. And since we intend Spanning Sync to be a useful service for not only English speakers but every Mac user in the world, we've localized the service into German, French, and Japanese, and plan to eventually support all 16 languages in which Google Calendar is available.

But Don't Take Our Word For It

Google Enterprise users have picked Spanning Sync as the #1 Top Rated solution on the Google Solutions Marketplace, with reviews like "Absolutely great", "Exactly what I was looking for", and "Just works."

Abilene Christian University's Associate CIO Jim Trietsch says, "Abilene Christian University has been using Spanning Sync since July 2007 shortly after we began using iPhones. We have been pleased with the product. The service has worked well and their tech support is always prompt and solves any problems."

RedMonk analyst Michael Coté says, "If you’re going to use iCal and you use Google Apps, you’ll need to get Spanning Sync."

David Chartier of The Unofficial Apple Weblog (TUAW) writes, "Spanning Sync looks to be the holy grail of true, two-way calendar synchronization between Apple's iCal and Google Calendar."

MacNN says, "If you want effortless synchronization between your Mac and Google, Spanning Sync is an easy program to use and rely on."

ZDNet writes, "$25 gets you a one-year subscription to the service. I consider it to be well worth the investment for the trouble-free way the utility helps me keep everything organized."

Wired News says, "It's understandable that Mac users are really excited about this."

InfoWorld writes, "For $75/user/year ($50/Google and $25/Spanning Sync) you have 10GB of email, shared calendar, Sync and whatever other goodies Google drops on you. Just over $6/user/month is well worth it to know all your data is available."

O'Grady's PowerPage says, "If you're ever wanted to use both Apple's iCal and Google Calendar and found yourself confounded by having to juggle two interfaces you owe it to yourself to check out Spanning Sync. It's a fantastic application that delivers on its promise and automatically syncs iCal and gCal behind the scenes."

Insanely Mac's Swad says, "Every so often there's an app released that is so simple, but so helpful, you wonder how you lived without it. Spanning Sync may just be one of those apps."

MacUser says, "I really like Spanning Sync. It has an easy-to-use interface, works great, and does exactly what I need: bidirectional syncing between Google Calendar and iCal."

Connect calls Spanning Sync Google Calendar's best friend: "I've been using it for the past 2 months and I can't live without it! It's a godsend for people using Google Apps like us here at Connect - everyone on the team can see what reviews are coming up, and they can make their own personal calendar privately."

MacZealots finds "synchronizational harmony": "Spanning Sync seems to be the holy grail for calendar junkies and those wanting a more dynamic experience than what .Mac's online calendaring service offers"

MACNOTES.DE sagt: "Alles in allem können wir Spanning Sync erneut beste Noten in allen (auch den neuen) Disziplinen bescheinigen."

MacVoices says: "Spanning Sync has been recognized by Google as a shining example of the type of software springing up around their online applications."
