Great article. Fun to see an app "launch" get salvaged, though of course the main takeaway (as usual) seems to be "get featured by Apple" (but you have absolutely no control over that, sorry). Not to fully discount the obvious effect that redoing the icon and screenshots had on sales in the midst of being featured, of course.
It's a great read, but I'm honestly struggling to read the text unless I highlight it first. Please change the colours to make it a bit easier to read :)
Thanks for sharing your experience. While it's great that your app got featured by Apple, it would have been more informative if you could have gauged the effect of your updates to the app before the Featured App effect kicked in.
