Drink water reminder apps nag you on a fixed timer all day, whether you have had water or not, and then lock the useful parts behind a subscription. SipUp is a water reminder and tracker built differently: reminders that actually adapt to your day, and with no ads ever.

YOUR PERSONAL HYDRATION NUMBER
*SipUp calculates a personal daily hydration number from your weight and activity level, based on established water-intake guidelines, not a generic "8 glasses a day" guess.
*No manual math. Update your weight or activity level anytime and your hydration number updates with it.

REMINDERS THAT ACTUALLY ADAPT
*Most fixed-timer water apps ping you on a schedule, regardless of whether you have had anything to drink. SipUp is different.
*Every time you log a sip, it recalculates how much water you still need and how much of the day is left, then re-paces your next reminder around that.
*Drink a big glass and your next reminder relaxes. Fall behind and it tightens up, automatically.
*Prefer a fixed schedule instead? Switch to a custom interval anytime and SipUp will follow it exactly.

SLEEP-AWARE, NOT JUST SILENCED
*Set your bedtime and wake time once, and reminders pause overnight automatically.
*Your very first reminder of the day fires within minutes of you actually waking and unlocking your phone. Not at a fixed clock time you might sleep straight through.

ALARMS YOU WON'T MISS, ON YOUR TERMS
*Built like a real alarm clock: SipUp can wake your screen and show up on your lock screen, not just quietly buzz somewhere you will miss it.
*Choose any ringtone already on your phone, or keep the built-in tune, and set the volume to whatever actually gets your attention.
*Busy or asleep? Snooze for 30 minutes, an hour, two hours, or until you actually wake up. SipUp waits for your next real unlock rather than guessing a time.
*Cannot drink right now? Tap Skip. Nothing is logged, nothing is judged, and your next reminder still arrives on schedule.

YOUR OWN GLASS, YOUR OWN PACE
*Not everyone drinks from the same size glass. Set your real glass or bottle size once.
*Every reminder, every quick-log button, and your whole daily water intake goal are built around your actual glass size, not a one-size-fits-all assumption.

A GLANCE FROM YOUR HOME SCREEN
*Add the SipUp widget and see how much water you have left for the day without even opening the app.
*Log a glass straight from your home screen with one tap.

SIGN IN, OR DO NOT: YOUR CALL
*Use SipUp as a guest and everything stays on your device. Nothing leaves your phone.
*Or sign in with Google or email to sync your progress, settings, and history across devices.

HISTORY THAT MEANS SOMETHING
*See your recent days at a glance.
*Watch your weekly and monthly averages build up honestly, based on what you actually logged, with no inflated numbers before you have the real data to back them.

WHY SIPUP IS DIFFERENT
Most hydration tracker apps fall into two camps: dumb timers that ping you at the same intervals no matter what, or feature-heavy apps that hide reminders, history, or customization behind a paywall. SipUp does neither. It's free, complete, and built around how your day actually goes.

YOUR DATA, RESPECTED
*SipUp never asks for your camera, microphone, contacts, location, or files. *Only what is needed to make a reminder ring.
*No ads. No data selling. Ever.

SipUp is for anyone tired of generic water tracker apps that ping on a rigid schedule and ignore how your day actually goes. If you want a water reminder that adapts to your pace, your glass, and your sleep schedule, this is the one built for that.

Stay hydrated the smart way. Download SipUp and let your reminders do the thinking.
