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.

Free on iPhone & Apple Watch

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.
