The developers at Infinite Kind aim to make the iPad a more useful tool for folks who want a whiteboard collaboration space, without all the hassle of getting everyone in the same place at the same time.
SyncSpace is a collaborative whiteboard for iPad. You can sketch out ideas and text on your own, but its real appeal is the ability to turn on syncing and let others draw with you in real time over the Internet.
The app is aimed squarely at distributed teams of application designers, Web developers, and other professionals who need to collaborate on a visual canvas, whether they're across the street or the continent. As of this writing, however, Infinite Kind had not responded to Macworld's request for comment on how many collaborators can work on a document at the same time.
SyncSpace boasts smart a smart offline mode; if you have to go offline while working or collaborating on a whiteboard, it can sync all your changes with your collaborators once you get your Internet back. It's also a vector-based drawing app, so you can zoom in pretty tight to make fine, detailed changes to your whiteboard.
Besides collaborating with others, SyncSpace can also share your creations on Twitter, Facebook, e-mail (as a high-resolution PDF), and 37signals's Campfire business chat service (which the company's own Draft can do as well).
SyncSpace is certainly not the first collaborative whiteboard for the iPad or iPhone. But it and Groupboard are the only two apps I can find that allow collaboration over the Internet, not just local Wi-Fi or Bluetooth connections. Groupboard takes a different approach, though, in that its app is free and allows up to five collaborators on a whiteboard; if you want more simultaneous participants, Groupboard offers paid monthly packages that start at 15-20 collaborators for $10 per month.
SyncSpace is $10 and available now in the App Store. Your iPad will need at least iOS 4.2 or later.
