Make it yours
Pick the color that feels right
Seven accent colors recolor the ring, buttons and highlights across the whole app. Light and dark themes included.

Your fast moves through six phases, from Just Eaten to Fat Burning, Deep Clean and Full Reset. Tauko shows your current phase, explains in plain words what is changing and counts down to the next one.
Pick a preset like 16:8, 18:6, 20:4, OMAD, 24 or 36 hours. With Pro you can set any length from 12 hours to 30 days.
You can import your history from a CSV or JSON file, so switching from another app is painless. Exporting to PDF or CSV is part of Pro. You can also clear your history or delete your account anytime from your profile.
The iOS app is coming to the App Store. It uses the same account, so your fasts and settings will be on web and iOS alike. Live Activity, the widget and Apple Watch are iOS-only.
No. Tauko is a tracking tool, not a medical service. Talk to your doctor before fasting, especially if you are pregnant or breastfeeding, have diabetes, take medication or have a history of eating disorders.
