H280

Your brain is made up of roughly 80% water, and staying hydrated plays a major role in memory, focus and energy. H₂O + 80% = H280.
Our goal is simple: make staying hydrated easier, so you can stay sharper and more focussed.

H280 was created to do one simple thing well: help you stay hydrated, without all the noise.

This clean, focused app does exactly what you need — no clutter, no tracking, and no sign-up required to get started.

Track your water intake with quick-add buttons, custom amounts, and intelligent reminders that keep you on track without nagging. Your hydration data is automatically synced with Apple Health.

No account is needed to use the core app.
Just install and go.
