answer:There is a web-app, just visit Ask-public.com on your iPhone and you’ll be redirected to the iPhone/iPod Touch-formatted version of the site. You can add it to your homescreen too, it has a custom icon. Considering you will be accessing the internet to use the app anyway, there isn’t much point using a native app, it works nicely in Safari. I wouldn’t expect to see a native Ask-public app (at least an official one) soon because it would take ages to code and it would basically be a waste of time that could be spent developing for the site. If they bring out an API, which would allow developers to access site data for programming apps that integrate with the site, we may see some native Ask-public apps made by 3rd Party Developers.
