This is built off Helco's PebbleLocalSim: https://github.com/Helco/PebbleLocalSim. Please see the readme.txt there for additional usage information. I have added support for the Dictionary, AppMessage, and AppSync APIs, along with support for the JavaScript API. You must have NodeJS installed for the JavaScript API. I have only added support for Linux. Adding support for other platforms should be straightforward. I make use fo the following: * https://github.com/driverdan/node-XMLHttpRequest/blob/master/lib/XMLHttpRequest.js. * https://github.com/ae-code/node-localStorage Testing of my changes have been very minimal. I was basically waiting for my Pebble watch (on backorder) to be delivered and was too excited to wait before getting started. The weather and quotes example faces should work well.
