About this app

Hydration Buddy — the water tracker that does the math other apps won't.

That coffee you just logged? It's only 83% hydration. That beer? Barely counts. Those spirits? They actually DEHYDRATE you. Hydration Buddy is the only water tracker that calculates net hydration based on real science.

FEATURES NO OTHER APP HAS
• Caffeine dehydration offset — coffee, tea, soda, energy drinks calculated at their true hydration value
• Alcohol dehydration math — beer (61%), wine (7%), spirits (NEGATIVE hydration)
• Overhydration safety warning — alerts if you log too much too fast (hyponatremia risk)
• Urine color chart — tap a color, get your hydration status instantly
• Food water content — watermelon, cucumber, soup count toward your goal
• Electrolyte awareness — warns when you need more than just water
• Time-of-day tips — "500ml in first 30 min of waking" and other science-backed guidance
