For the high fidelity design, which was done on Adobe XD, although I wanted to focus more on aesthetics (as is the nature of high fidelity designs), I also found opportunities to improve the medium fidelity design.
For example, I realized that the “Completed Tasks” menu needs to be consistent across all screens. That means it needs to either on default always list all tasks, or simply be a drop-down menu. For the sake of simplicity, I chose the latter. Furthermore, the phrase, “What do you want to do today?” implies that the user can only add tasks for today, which is not the case. So, I changed that as well to “What do you want to do?” I also added the ability to label tasks, to make organizing and searching for tasks easier.
