A health application is a (medical) aid to assist the user in the process of healthcare provision or healthcare consumption. It is therefore paramount that users are informed about the good usage and practices when handling a health application. We thus recommend the app to:

• Inform users it does not replace the services provided by a healthcare professional and that in case of a serious problem or injury a healthcare professional should be consulted.
• Notify users about possible risks for patient safety caused using the app. Known risks and adverse events can be notified by users and must be analyzed and mitigated with undue delay.

Furthermore, app developers and vendors should analyze known risks and adverse events (near misses) and develop convenient actions.
