One honest number out of 100 — built from what you drink and what your body says back. 100 means you've found your personal optimum.
The honest hydration app for iPhone
Most people are under-hydrated — and don't know it.
Meet Pal. A few quick questions and we'll find your hydration score.

Water changes everything
Mild dehydration is invisible — you just feel a bit off. Here's what's really going on.
60%
of your body is water. It runs everything — temperature, joints, brain.
−2%
of water loss is enough to dent your energy, mood and focus.
33ml
per kg of body weight — your real daily need. Not a generic “8 glasses”.
⚡️
More energy, less fatigue
Fatigue is often thirst in disguise. Steady hydration keeps the afternoon dip away.
🎯
Sharper focus
Your brain is ~75% water. Even mild dehydration slows reaction time and memory.
✨
Healthier skin
Well-hydrated skin is more elastic and looks plumper — water works from the inside.
🧠
Fewer headaches
Dehydration is one of the most common headache triggers — and the easiest to fix.
