We're pretty excited about iOS 7 and the opportunities it will afford. The short-term downside is that we will have to invest significant effort into updating the appearance of our apps at the expense of new functionality. However, Apple has given us good tools to assist in moving forward, and the new OS will enable even more significant improvements to the user experience than we had already planned.
Those of you still running our apps on iOS 5.x should note that we, like many other developers, will probably be dropping support for iOS 5 in the releases that are enabled for iOS 7. You will be able to run the current versions on iOS 5 indefinitely, but you will be cut off from new features. Since iOS 6 has something like 95% adoption already, we think this is a small price to pay for progress.
We submitted Eye Tide 2.0.1 to the App Store today to fix a problem: when we added map-based station selection to the app, we neglected to update the "Recent Stations" list in the Locations menu.
