We're constantly working to improve TinyApp, both in terms of feedback and according to our own plans. We are also constantly making updates related to security and usability among other things. Therefore, we prefer to publish often to keep the app as updated as possible.
This allows for better quality application updates. Our users have countless combinations of different phone model, operating systems and TinyApp versions, so the frequent pace of updates allows us to respond quickly to a variety of user issues that unfortunately may occur from time to time.
