I decided to load up Cookie Monster for the first time the other day. It pretty much just does what my spreadsheet already did, except with more lag. Well, that's not entirely true, the Golden Cookie features are really helpful. I like that I can put numbers into 'scientific notation' but it bugs me that they don't actually use proper standard scientific notation, since it does [1-1000)*10^(3x) and not [1-10)*10^x as it should. If I could work out how, that's one thing I'd change with it.
