Filamente is an upcoming iPad app that is a native client for Sharepoint. It’s described thusly in their Twitter bio:
Filamente, a native iPad client for SharePoint, allows you to perform various tasks that you cannot do using a regular web browser on your Apple iPad
I haven’t found a lot of details on the app as yet – other than a few screenshots here. Then again, I haven’t seen many iOS apps at all – and none for the iPad – that act as Sharepoint clients. It’s been a long while since I had any exposure to Sharepoint, but whenever I did I thought it was very impressive – so I would imagine iPad Sharepoint client apps could be a big deal for many corporate users.
Filamente is expected to be released on the App Store on September 12, at an introductory price of $2.99. In the meantime, you can follow @filamente on Twitter for news.
