<p>The purpose of the Isle of Wight phase is to improve the user experience of the National Health Service COVID-19 contact tracing application and to understand the effectiveness of the Test and Trace programme. Uptake and correct usage of the app is important and we have engaged with residents on the Isle of Wight about how the app operates, why people choose not to have it, and their attitudes towards it and the wider Test and Trace programme. Alongside these, we are measuring quantitative measures such as usage and download rates. Just like any high-quality app, we will continually improve it over the coming weeks for optimal functionality as data continues to come in.</p>
