My best (and most difficult) iPhone application has just hit the iTunes Store. Sole Man is an app to bring with you to the market when buying seafood. For each item in the list, it displays a picture, the scientific name, the sushi name (if any), other names it goes by, a kosher indication, any health concerns (mercury, PCBs, etc.) to watch out for, environmental issues (endangered status, bad fishing practices, etc.), and other notes such as what fish to substitute for species with health or environmental issues.
