Get a notification when flu, COVID or RSV rise in your country. InfectRisk shows an estimate of your infection risk for today, adjusted to your age and health, with everyday advice to match. How it works The app combines official surveillance data (for example from CDC and ECDC), wastewater monitoring where available and estimates of infections that never get reported. Wastewater is an extra signal that often shows a new wave before case numbers do. The result is one simple level for today. The app updates every day, and each source reports on its own schedule. What you get - An estimate of your risk for today - A notification when the level in your country rises - Everyday advice for your level: what to avoid and what to do with care - Flu, COVID and RSV separately, with trend and charts over 3, 6 and 16 months - A Home Screen widget - Global outbreaks from WHO and ECDC, briefly explained in your language - Share warnings with your family - 35 countries in Europe, Asia and the US, in 11 languages - No ads, no account For anyone who would rather check than guess. Especially if you are over 60, care for someone at higher risk, or have little ones who bring home every bug from daycare. Pricing The first 7 days are free, with every feature. After that, a yearly subscription or a one-time purchase keeps your risk visible. All figures are estimates. InfectRisk is not a medical device and does not replace medical advice. For decisions about your health, talk to your doctor. The app collects anonymous usage statistics to improve.
