I personally loved this idea!
I designed the app to look smooth and trendy at the same time. I tried to incorporate important features into the design. Homescreen has two options either to get tested for covid or to get vaccinated. Based on the option selected the list of nearby locations will get displayed in the below section starting with the nearest point.
After selecting a location, users need to choose the date, time and fill up their personal details...hola! Your slot is confirmed!
Thanks, Crowwwn for coming up with such creative ideas every week!
