Water Intake Tracker
Stay hydrated. Log your water intake throughout the day and see your weekly trends.
Water is essential for every system in your body — it regulates temperature, lubricates joints, transports nutrients, and helps flush waste. Your daily water needs depend on your body weight, activity level, and environment. A common guideline is to consume 30-40 milliliters per kilogram of body weight as a baseline, with additional water needed during exercise and in hot climates.
Dehydration of as little as 1-2% of body weight can impair physical performance, cognitive function, and mood. Signs you may need more water include dark urine, fatigue, headache, and dry mouth. For active individuals, drinking 500-750 ml (17-25 oz) of water 2-3 hours before exercise and sipping throughout your workout helps maintain performance.
This calculator adjusts your baseline for exercise duration and climate. Remember that water from food (fruits, vegetables, soups) contributes to your total intake — typically about 20% of your needs. If you are tracking macros, pair this with our Macro Calculator for a complete nutrition plan.

Why Hydration Matters
- Improves workout performance — Even 2% dehydration can reduce strength, endurance, and focus during exercise.
- Aids recovery — Water transports nutrients to muscles and flushes out metabolic waste products after training.
- Regulates body temperature — Proper hydration helps your body cool itself efficiently during intense workouts.
- Supports weight management — Drinking water before meals can reduce calorie intake and boost metabolism temporarily.
General guideline: 30-40 ml per kg of body weight, adjusted for activity level and climate.
