I've created added an updated scoring module for Ryan Christianson's Score app for iOS. This now includes the San Juan expansion buildings. If you already have this app, go to Setup>Manage Score Modules and use this URL: http://tinyurl.com/ScoreModulesBySD40 and click Fetch. This will add the San Juan+Expansion module to your existing modules, as well as the other modules I have created for Agricola: ACBS, Castles of Burgundy, and Stone Age.
There's a few steps to get all the modules: 1. download/install app 2. go to Setup, then Manage Score Modules. You'll see a URL showing http://tinyurl.com/scoremods. Click on Fetch to load a number of modules created since the last update for the app. 3. now change the URL to http://tinyurl.com/ScoreModulesBySD40 and click Fetch to load my modules listed above.
