We built an app called CS Protect that helps fight Covid by allowing users to check-in at businesses across Scotland. The platform was created in around four days using the no-code tool Bubble, which allows for quick creation of robust platforms and rapid changes. By signing up once, guests can store their visits at multiple locations without having to hand over their contact details to each individual business. The app has expanded into 17 separate apps for different areas of Scotland, with over 600,000 users and 1000 locations using the platform, and has been featured in news stories across the country. We aim to eventually "end" our need for the platform as it serves its purpose in fighting Covid.
