Yesterday, Google officially launched the Google Glass Developer Kit (GDK) that allows developers to build glassware that works in a more integrated way with Glass.

Part of the announcement of the GDK was to launch several Glassware apps that utilize the service.

The five third-party glassware apps introduced at the event were:

Allthecooks: A cooking app to help you read recipes without using your hands.
Spellista: A word jumble game.
GolfSight: A tool to calculate distances and the like as you wear silly pants and wave sticks at small round objects.
Strava: A run tracking app.
Wordlens: Translate printed words into a language you can understand

Google themselves made a few simple glassware including:

Compass
Stop Clock
Time

Plus there were a few glassware apps released by third-party developers approved yesterday including:
IFTTT: IFTTT is a service that lets you create powerful connections with one simple statement — if this then that.
Jewish Guide for Glass: A companion for observant Jewish people. Reminds you to pray, where to pray, what to pray and much more.
Umano: With Umano you will hear REAL voice actors read interesting news articles to you.

Here is a video of the event:

Disclosure, my company built the Jewish Guide for Glass, more details over here.
