I completely agree, one of the reasons that we've been reluctant to release is that we've been developing a native app. Considering how long it takes to push a bug fix, with Apple approving and all, you can expect 4 days of downtime if you really screw up.

If you compare that with web, as many pointed out my article had a lot of spelling errors but that was easily corrected.

The real challenge is testing your assumptions without ever releasing an app or website :)
