Mark Jardine:
Seven months ago, we started working on a big update for Calcbot. We were hoping to release it sometime in the summer. Two months in, Apple announced iOS7 at WWDC. We knew this was a huge change. It would make every single one of our apps look dated so we had to make sure our flagship app was ready for it. All of the design work that went into the Calcbot update was rendered obsolete in one keynote and so we focused our energy on updating Tweetbot for iPhone. Playing with the beta of iOS7 over the next few weeks brought us to the realization that this would not just be a “re-skin”. We really had to just start over with the new foundation and concepts of iOS7.
