Health made simple
The DIOPTRA app helps you to understand complex medical information. It simplifies terms and concepts about colorectal cancer screening, prevention, and care, helping you understand your options, have better conversations with doctors, and make confident health decisions.
Your personal helper
DIOPTRA mobile app looks at your lifestyle habits, such as what you eat, if you smoke, how active you are, your alcohol consumption, etc. It helps identify patterns in your behaviour and highlights areas where you can make changes to improve your health.
Based on your profile, it provides suggestions to address modifiable factors such as dietary habits, physical activity, and daily routines. To support you in making these changes, the application provides specific articles, offering practical guidance to help you follow them.
