Could be better.
There is a significant delay between opening the app and when you can actually interact with it, it was quicker to go directly to the website online to obtain screening times.
Serviceable
The buttons were a bit unresponsive and it’s impossible to make an account, however once the site had loaded there is very limited lag or stuttering. It still tells you to install the app, on the app. However it does do its job and with a few touch ups it would be very good. Thanks :)
