The app was to be used primarily be a demographic of users aged 40 and above, and hence various design considerations in terms of font colors and sizes had to be taken into account. I started off with creating some user personas (primary and secondary users) who would be using the app, based on which I participated in generating some user stories to help understand the overall scope and requirements of the app.
Once the user stories and various case scenarios were finalized, I started off with some preliminary sketches and prototypes, with a paper and pencil being one of my favorite tools for generating some low-fidelity prototypes. Various iterations and tweaks were made based on the initial feedback after testing the prototypes with a focus group. The final mock-ups were created using Sketch and tested through InvisionApp. Sketch actually proved to be quite helpful in generating assets for various resolutions; x, 2x & 3x for iOS and hdpi, mdpi, xhdpi, xxhdpi and xxxhdpi for Android. I also made use of some of the great plugins Sketch had to offer in terms of collaboration with the developers, Measure being one of them. I also created some animations to explain some of the various interactions I envisioned in terms of overall UX of components within the app; calendar (listing down the daily activities and events for senior communities) being one of them. Overall, I created around 25 screens (for each app) and dozens of interactions within!
