As a Glass Explorer, I'm always excited to see new apps, especially if they improve Glass' user experience. Developer Matthew Pierce delivered one such app recently, making Glass Master Control available to the public via Dropbox.
Essentially, Master Control allows users to change Glass settings in a new, more fine-grained way. It controls volume, brightness, and radios (Wi-Fi, Bluetooth, and AutoSync). Until now, Glass hasn't had manual brightness controls, and volume control was buried in a settings card at the very left end of the timeline.
Where volume is concerned, Master Control allows users to turn volume up, down, or set it to maximum or mute. Users can also toggle auto brightness, and - like volume - choose maximum, minimum, or any step in between. Finally, users can toggle Wi-Fi, Bluetooth, and AutoSync, or choose to toggle all at once. All of the settings can be controlled with voice commands and touch gestures, explained in Pierce's Google+ post linked below.
The app also has a Status screen, which will show (and read to) users the status of all the above settings, plus battery level.
If you're an explorer looking for a handy new app that, while still a little rough around the edges, provides pretty awesome control over your Glass unit, check out Pierce's Google+ post linked below for the download link and gesture instructions.
