Version 1.0 Lessons Learned App Store Distribution Inexpensive ($99/year) way to reach an extremely large audience First week in app store = 281 downloads, 38 countries But developer is at the mercy of Apple. They can reject an app for any reason. ESRB Ratings The caBIO app was rejected twice for “mature” language in the OrganOntology object. Names of sex organs are considered mature even in a medical context. Each rejection requires another full review even if the change is minor (i.e. rating metadata). Resolution: app is now rated “Ages 9+”

Version 1.1 Fixed navigation bug with initial query Previous 50 queries now cached, back/forward navigation is instant Added “reload” button Safari-like navigation button icons
