We’ve been collaborating with the client on this app from very initial stages. First we’ve developed a dummy mockup app, so he could see how it will look like, again because we’ve used web technologies it was very simple to share and for him to review. Then after a few back and forth changes we’ve implemented the logic part: authentication, saving notes, etc. After the app was published, we’ve gone in second phase where we’ve started implementing some of the more advanced scenarios. As of this writing we’re still in an active development phase, but we already can see that this app changed quite a bit the client ideas, and because of publishing this app, he could think of next steps, bringing in new features, even in some cases pivoting the general idea of the app.
