ok... i saw your app:
i like the idea.
id fix:
-$11.99 is a bit steep, especially considering it only lets you add temp gauges and x10 control.
-the ui interface good use some work... make it look like an apple made app, more professional. at the very least, change the purple background to white, so the buttons dont look weird.
id add the ability to:
-theme the app.
- allow any iobridge widget or display. you could do this by asking for a widget variable, and then adding it into the javascript.
