Google jumpstarts Glass development with apps from Twitter, Facebook and Evernote

One of the biggest gripes about Google Glass (s goog) has been it doesn’t have any apps. Well, some of the biggest app developers and content providers in the world have decided to rectify that problem. On Thursday, Facebook(s fb), Twitter, Evernote and CNN(s twx) along with a handful of other content providers announced that they have already created or are in the process of developing apps — dubbed “Glassware” — for Google’s new headgear.

In a blog post, Twitter said you can now tweet photos from Glass to your feed — the update will include the hashtag “#throughglass” — and see your other tweets by turning on in-Glass notifications. The service is now available and users can activate the Twitter app on Google’s MyGlass portal.

Facebook’s Glass implementation is also live, though for now you can only share photos, not post status updates or view your newsfeed. You can, however, set privacy levels and add descriptions to photos you post using Glass’s speech recognition features.

Evernote doesn’t yet have an app per se, but it is integrating with Glass’s sharing menu, allowing you to capture a picture or short video and save it as a note in your Evernote account. It is also giving users the option of sending notes (from its web app) to the Glass timeline so your grocery list or crib notes are right in your line of vision.

At I/O Google revealed three other companies taking up shop on Glass. CNN’s app will put news alerts in front of your retinas. Elle is providing content from its magazines that can be viewed in the Glass display or read aloud. Tumblr lets you post content to your personal blog and get updates from Tumblrs you follow.

These companies join Path and the New York Times as the only official third-party apps on the Glass. For now Google is being rather conservative in its Glassware efforts, placing restrictions on the level of access to platform and banning ads or any other monetization scheme.

Still, once Google fully opens up Glass, it likely won’t have any shortage of interest. Smaller developers are already clamoring to get on board. For instance, Open Garden wants Google to expose Glass’s networking functions so it can link the headgear to its crowdsourced mesh network.
