> Dayzeroo je česká aplikace pro sledování závislostí a návyků. Zdarma, bez reklam, česky.

Dayzeroo (dayzeroo.app) is a Czech app for tracking addictions and habits. Users can track alcohol, smoking, phone time, drugs, medication, sugar and gambling directly in a browser. It is a Progressive Web App, so no App Store or Google Play download is needed. It is free, ad-free, GDPR compliant with data stored in the EU, and fully localized in Czech and English.

Core features: daily tracking for selected areas, personal limits and abstinence goals, streaks, savings, mood and craving diary, progress views, crisis support, friends and an anonymous Czech support community. Alcohol remains the most detailed area, with a BAC calculator, withdrawal timeline and dedicated evidence-based content. Dayzeroo is a tracking and support tool, not medical advice or treatment.
