Interesting read. Can I just ask, why are you guys giving up so easily? It seems like you only launched Whim 3 months ago. Granted it might not have been successful as you anticipated but you shouldn't shut it down.
I've released a few apps on both the Android and iPhone stores and the hardest lesson I've learnt is that creating a great app is only half the battle. There are over 500k apps on there. Chances are most people don't even know it exists.
Instead of shutting down and moving on you should continue supporting it. You need to build a community. When you release your next app you can use existing apps to advertise new ones. People will recognise your work on the appstore if you provide great support.
Some good points as far as getting noticed in the app store. We're definitely not giving up, though. We've submitted a new app which is a pretty big follow-up to Whim based on What we learned, but is fundamentally different enough to not be called Whim. In addition there were some legal issues with the name "Whim", so it made sense to just shut down the app and focus fully on the next app we've submitted.
