Schedule totals 2.15 L. Servings are rounded to 50 ml, and nothing is scheduled in the 90 minutes before bed so you sleep through. Attach each drink to something you already do — coffee, meals, meetings — and let an app like Realwater send the reminders so you don't have to remember the clock.

Estimates only, for healthy people. Not medical advice — if you have a condition that affects fluid balance, follow your doctor's guidance.

Why a schedule beats willpower

Most people don't fail at hydration because they don't know their number. They fail because 3 p.m. arrives and they've had one coffee. Turning a total into fixed moments removes the decision: it's 10:30, so it's a glass. Our guide to remembering to drink water covers the psychology; this tool builds the timetable.

How the schedule is built

The first drink is the largest, up to 500 ml, because you wake mildly dehydrated after seven or eight hours without fluid. The remainder is split evenly across your chosen interval until 90 minutes before bed, and if you add a workout time it earns its own slot. Servings are rounded to 50 ml so they map onto real glasses. If you don't know your goal, start with the daily water intake calculator.

Anchor drinks to things you already do

A time on a list is easy to miss; a habit attached to an existing one is not. Match the schedule's slots to your coffee, your meals, the school run, the end of a meeting. A simple morning routine covers the first and most important glass almost automatically.

Let the phone do the remembering

You could set alarms for every slot, but a hydration app is built for exactly this. Realwater's reminders follow your active hours, skip a nudge if you just logged a drink, and go quiet at night — so the schedule runs itself and you just tap when you drink. For the evening end of the timetable, see water before bed.

Frequently asked questions

How often should I drink water throughout the day?
Every 1–2 hours while awake works well for most people. Regular smaller drinks are absorbed better and keep you steadier than a few large ones.
What is the best time to drink water?
A glass on waking replaces overnight losses; a glass with each meal is easy to remember; a drink before and after exercise covers sweat. Beyond that, timing matters less than spreading it out.
When should I stop drinking water before bed?
Taper in the last 1–2 hours before sleep so you're not woken by your bladder. A small sip if you're thirsty is fine; a large glass at lights-out isn't.
Should I drink water on a schedule or when thirsty?
Both. Thirst is a reliable signal but a slow one, and it's easy to ignore when busy. A light schedule fills the gaps; thirst tells you when to add more.
