The 'Medicines and Healthcare products Regulatory Agency' (MHRA) has issues updated guidance to help identify the health apps which are medical devices and make sure they comply with regulations and are acceptably safe.

The guidance is presented as a step-by-step interactive PDF. App users can use this guidance to check if their health app is a medical device, and what to look for to make sure the app is safe and works.
