Vessel: Water Tracker
Hydration, Caffeine & Drinks
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Vessel is the smartest way to track your daily hydration. Unlike other apps that count every drink equally, Vessel uses real peer-reviewed research to show you how hydrating your drinks actually are.
WHY VESSEL IS DIFFERENT
• Scientific hydration multipliers — coffee counts as 92% hydrating (Killer et al. 2014), beer at -10%, spirits at -50%
• Beautiful ocean-depth progress ring that deepens as you drink more
• Built-in health warnings for excess caffeine, alcohol, and overhydration
FEATURES
• Fast logging — one tap to add water, coffee, tea, beer, wine, and more
• Daily progress ring with smooth water wave animation
• Celebration when you hit your goal
• 12 achievement badges for streaks and milestones
• Week / Month / 3-Month charts with color-coded drink breakdown
• Hydration Science page with cited research
• Smart reminders at your chosen hours
• Apple Health sync for water and caffeine
• Body weight-based goal calculator
• Dark mode support
• Ounces, milliliters, and liters
HEALTH WARNINGS
Vessel alerts you when:
• Caffeine exceeds FDA's 400mg/day limit
• Alcohol intake crosses CDC moderate drinking guidelines
• Water intake approaches levels that risk hyponatremia (over 3.5L/day)
YOUR DATA, PRIVATE
All drink data stays on your device. Optional Apple Health sync is fully under your control. No accounts, no tracking, no ads.
Drink smarter, not just more.
