I released an update for the This Day app. I redesigned it for iOS 7 (which is roughly the same as removing almost all styling altogether). In my opinion it became nicer and more concise.
I used the standard UIActivityViewController for sharing via Facebook, Twitter, and other built-in options such as email, sms/iMessage, etc., and I also added Vkontakte-iOS-SDK for sharing to VK instead of the homemade thing that had been there before. True, there are not really any visual differences for the user, and by the time I finally got around to polishing everything, VK had already released an official iOS SDK, but I did not want to dig into it just to replace something that was already working.
At the same time I got rid of the now unnecessary SBJson for working with JSON, because you can safely use the NSJSONSerialization already built into iOS. I decided to add Yandex.Metrica Mobile to the app to count users properly and see, for example, who uses which iOS version and on what device. For now I am just watching the numbers; it is informative.
This is how the little hobby project continues. I will think about what else to build into it, and then I will write the next app. For now — download/update:
