HydrateMe: Water Reminder

Water reminders that actually show up. A tracker that never asks you to pay.

Most drink-water apps fail in the same three ways: the reminder arrives an hour late, the useful half is behind a subscription, and an ad covers the button you were reaching for. HydrateMe is built against all three.

REMINDERS THAT ARRIVE ON TIME

HydrateMe schedules exact alarms, so a reminder set for 10:30 arrives at 10:30 — not whenever the system gets around to batching background work. Reminders survive a reboot. They never stack up into a pile of identical notifications. And they stay inside the waking window you choose, including overnight windows if you work nights.

LOG WITHOUT OPENING THE APP

Every reminder carries "Log 250 ml" and "Log 500 ml" buttons — one tap from the notification shade and you are done. The home-screen widget has a plus button that does the same. So does a long-press on the app icon. All three write through the identical logging path, so your total is always the same number.

SMART ENOUGH TO STAY QUIET

Smart snooze skips a reminder if you already drank something in the last few minutes, so it never nags you right after a glass. Pause-when-goal-met stops the reminders once you have hit your target for the day. Both are toggles you own.

SIX DRINKS, HONEST MATH

Water and sparkling water count fully. Tea and juice count at 95%, coffee at 90%, smoothies at 85% — because not every cup hydrates equally. Each log stores the coefficient it was made with, so your history stays accurate forever.

A GOAL YOU CONTROL

Onboarding takes four steps and can be skipped entirely. Your goal is calculated from your weight and activity level, with a live preview as you type — and you can override it with your own number at any point, in onboarding or in Settings. No app should tell you that you are not allowed to change your own target.

BACKDATING IS FREE

Forgot to log this morning? Long-press an amount and set the time. Past days can be edited from the History calendar too. Rival apps charge for this. Ours is free, including across midnight.

HISTORY, STREAKS, AND ONE FORGIVING DAY

A month calendar shows every day colour-coded by how close you came. Tap any day to see and edit what you logged. Your current and longest streaks sit above it — and if you miss a day, a weekly Streak Rescue can save it once. Encouraging, never shaming.

HOME-SCREEN WIDGET

Progress at a glance plus one-tap logging, resizable from 2x1 to 2x2. Free, like everything else.

YOUR DATA IS YOURS

Export a CSV, or take a full JSON backup you can restore later. Restore is transactional — a bad file is rejected without touching what you already have. Clear everything from Settings whenever you want.

NO ADS. NO PAYWALL. NO ACCOUNT. NO INTERNET.

Not "ad-free for now" — this version contains no advertising code at all. Nothing is locked behind a purchase, because there are no purchases. There is no sign-up, and no "no connection" screen, because HydrateMe never touches the network. It does not even request internet permission.

Also: millilitres or ounces, light and dark themes, and a quiet confetti moment when you hit 100%.

HydrateMe estimates a daily target from your weight and activity level. It is a habit tracker, not a medical device, and gives no medical advice — which is exactly why the goal is always yours to override.
