The biggest challenge while working on the app was its interface. I had to ensure that the app presents the information clearly and quickly, but at the same time doesn’t overwhelm already stressed user. Another aspect was the app’s accessibility; while working for user group with very diverse needs often opposing each other, I had to find the perfect balance for each element. Due to the fact I couldn’t test my idea, it was very difficult to develop the idea. I had to put myself in the user’s position to the best of my ability and see if the position, size, colour of the elements and image representation like emojis are helpful.
