I finally installed my OpenGarage a few days ago and now have developed an app to control it. The first version is working now however I am going to try and add a few more features before publishing to the app stores. The app is built on AngularJS and Ionic.
For now, Android users may install the app from the PhoneGap Build link above so long they allow 3rd party apps. Soon, a web app version will be hosted as well as the app store versions. Please post any problems/bugs and I will try to hammer them out. The app has currently only been tested on my setup. With all of that said, Enjoy!
