It's 3 PM. Your head hurts. Your focus is gone.
You blame the workload. It's the water.
of deep work, zero sips
Flow state is a superpower. It also switches off your thirst. You don't forget on purpose. You just never get the signal.
dehydration dulls your brain
That's all it takes for focus, memory and mood to measurably drop. The afternoon crash you keep blaming on work? Often just thirst.
reminders where you work
Every water app lives on your phone. Your phone is face-down across the room. The reminder fires. Nobody's there.
You don't need more discipline.
You need someone on your screen who notices.
Pick the buddy who gets you
Each one reminds you in their own voice. All of them actually care.
Jay
"The bottle's right there. Easiest win of your day."
Ava
"Blocking 30 seconds on your calendar for a sip. Accept?"
Umi
"You've been working so hard. One glass, then back to it. Deal?"
Kai
"So… the water's just decorative, then?"
Nami
"SIP ALERT!! 🌊 Tiny break, big glow!"
Three steps. Zero effort.
Pick your buddy
Open sippu.app and pick from five characters. A progress ring fills as you drink.
They check in, kindly
A little card slides in with a line that makes you smile. Two buttons: "I drank 💧" or "Snooze 15 min". That's it.
Watch your streak grow
One click logs it. Your buddy celebrates, your streak builds, your afternoons stop crashing.
Sippu never, ever nags.
Busy? Snooze it. Here's exactly what happens next. We call it the politeness ladder:
"Welcome back 💙 No rush. Whenever you get a second, water's still here."
"No pressure at all. Just a tiny sip when you can."
"You're clearly in the zone! I'll catch you at the next one."
...and Sippu goes quiet until the next hour.
Respecting your focus is the whole point. A reminder you'd mute isn't a reminder.
Every sip does real work
Sippu tells you what each glass actually does, so it never feels like a chore.
Sharper focus ðŸ§
Even 1-2% dehydration measurably dips concentration and short-term memory. That 3 PM fog? Often just thirst.
Real energy âš¡
Fatigue is one of the first signs of dehydration. A glass of water is cheaper than another coffee, and it works.
Fewer headaches 💆
Steady water intake is one of the simplest ways to keep dehydration headaches from ending your day early.

Questions, answered
Won't this distract me while I work?
The opposite. It's built around your focus. Reminders come about once an hour (you choose 30–120 min), respect Do Not Disturb, and back off automatically when you're busy. Dismissing one takes literally one click.
Which devices does it work on?
Sippu works on Mac, Windows and Linux today. Open it in your browser and click Install to get a dock or taskbar icon and its own app window, with reminders that reach you while you work in other apps. Native downloads for Mac and Windows are in development, and a mobile companion is on the roadmap.
Is my data private?
Completely. If you use Sippu without an account, everything stays in your browser and never reaches us. If you create an account so your streaks sync across devices, we store only your email and your water logs. We never sell data.
Is this a subscription?
No subscription at all. Try it free for 14 days, then a single $5 payment unlocks Sippu forever. No renewals, nothing to cancel, no surprise charges.
Ready to stop forgetting?
It starts with a single sip. Open Sippu in your browser and meet your buddy in under a minute. Two weeks free, then one $5 payment and it is yours for good. Your future self says thanks.
