Evaluating digital health products
Resources to help anyone developing or running a digital health product to conduct an evaluation.
It’s important to conduct evaluations for all digital health products.
Evaluation is useful whether you are developing your product or have already launched it.
These resources will help you to carry out evaluations. They are intended for anyone developing or running a digital health product. They can be applied to all types of digital health products (for example, a service, campaign or other intervention) and ways of providing products (for example, through an app or website).
If you are working on non-digital services, go to Evaluation in health and wellbeing for more general health evaluation advice.
