About
You know you should drink more water. Yet by 5 PM, your mouth is dry, your head hurts, and your bottle is still sitting full on your desk.
Most water trackers fail you for two reasons: they turn logging into a math chore, or they spam you with mindless alarms until you mute them forever.
Stay Hydrated fixes both. It turns hydration into one effortless daily job: empty your bottle before bed.
SEE WHAT DEHYDRATION ACTUALLY FEELS LIKE
It is easy to ignore a progress bar. It is hard to ignore your kidney.
Meet your kidney buddy—it sits right next to your bottle and reacts to every glass you drink. Keep up with your pace and it glows. Neglect it for a few days and it dries out like a sponge until painful-looking pebbles start to form. The only way to break them down? Finish your bottle, one day at a time.
STOP DOING MILLILITER MATH
Forget counting ounces or staring at confusing charts.
- Your virtual bottle starts full every morning and drains as you drink.
- One glance tells you exactly how much water you have left to finish your day.
- Log a sip, a glass, or a big glass in a single tap—each drink leaves its timestamp right on the bottle.
END NOTIFICATION FATIGUE
You do not need an alarm when you are already hydrated, and you definitely do not need one while you sleep.
- Stay Hydrated only pings you while you are awake, and ONLY when you are falling behind your daily pace.
- Log your drink straight from the notification without even opening the app.
OUT OF SIGHT, OUT OF MIND? NOT ANYMORE
- Keep your draining bottle and your kidney's live mood on your Lock Screen and Home Screen widgets so you never forget to sip.
- Every finished day adds an empty bottle to your personal shelf. Build your streak, and see exactly how much water was left behind on the days you missed.
- Tap your kidney anytime to share its current mood—from bone dry to glowing—as a sticker with friends.
