Here's an idea. I need to create a sample mobile application for a class I'm teaching in the Spring. I had the idea to create an absinthe dilution calculator app based upon the Absinthe Dilution Matrix. Going beyond this though - including a database of popular brands which would display the correct ratios automatically with the ability for users to add their own favorite brands as well.
Would anyone find such an app useful? I'll probably take this idea and run with it for the class - but would actually publish it to Google Play as a free app if others would benefit from such a thing.
