HydroFast: Fasting & Water

Build a simple daily rhythm with HydroFast, a private fasting and water tracker that works without an account.

FASTING AT A GLANCE

Choose a 14:10, 16:8, or 18:6 fasting plan and follow your progress with a clear timer. HydroFast restores an active fast after the app restarts and shows elapsed time, remaining time, and approximate fasting phases. Finish a completed fast, save an early finish, or discard a session you started by mistake.

QUICK WATER TRACKING

Log common glasses, cups, and bottles in a few taps, or enter a custom amount. Set your daily goal and view progress in milliliters or US fluid ounces. Undo an accidental entry without leaving the Home screen.

HISTORY THAT STAYS USEFUL

Review weekly and monthly fasting and hydration summaries, completed sessions, daily water totals, progress charts, and current and best streaks.

OPTIONAL LOCAL REMINDERS

Enable hydration reminders and fast-end alerts when they help. Notifications are scheduled on your device and can be turned off at any time.

PRIVATE BY DEFAULT

Your fasting records, water logs, goals, and preferences stay in the app's local database on your device. HydroFast does not require an account, advertising SDK, or cloud connection for its core features.

HydroFast v1 is free. It includes the standard fasting plans, water tracking, history, streaks, themes, unit preferences, goals, and local reminders without a paywall.

WELLNESS NOTICE

HydroFast is a general wellness tracker, not a medical device. Fasting phase labels are approximate educational estimates and do not guarantee a biological outcome. Consult a qualified healthcare professional before fasting if you are pregnant or breastfeeding, under 18, have a medical condition or history of disordered eating, or take medication affected by food or fluid intake.
