“Dermdaly”, writing for the Tapadoos blog, on updating apps to fit iOS 7's design:
I predict the iOS 7 effect will be worse. Within a week of running full time, those apps which haven’t been modernised to look like an iOS 7 app will look very old. They too will become insta-deletes.
If you have an app in the store, We’d highly recommend looking at modernising them pretty quick.
Of the apps I use most often, I’m very curious to see what Tapbots does with Tweetbot. I’ve seen several reports on Twitter that Tweetbot looks horribly out of place on the iOS 7 beta. Conversely, Day One and Twitterrific would seem to feel right at home within the new design.
