This is the most useful app on my iPod Touch. It works offline, and will also work through multiple stops (including busses, trains and ferries) and includes accounting for missing the closest connection at that given stop on the way. It only has one downside and thats the map access. Updating the city/stop map when offline (as is the case of the iPod Touch when on foot) is extremely limited. If it had its own build in map of the Sydney area, it would be absolutely perfect. But as it is it is definitely worth the purchase.
