Hydrate is the AI hydration coach that knows your cycle, your schedule, and exactly what to say to get you to your last ounce. Pick your coach — Stacy, Lex, Lily, or Jade — and let her handle the rest.
No spam — just early access and founding member pricing.
Generic apps send everyone the same robotic reminder. Hydrate gives you a coach with a name, a personality, and opinions about your water intake. Switch vibes any time — they all want the same thing for you.
Witty, bold, and a little extra
“It's 3 pm and you've had 14 oz. The headache you're brewing is not the aesthetic.”
Data-driven, no excuses, all results
“You're at 60% with 4 hours left. Two 12 oz glasses and you hit goal. No excuses.”
Warm, encouraging, zero pressure
“A little sip now and you're right back on track. You're doing beautifully — no pressure, ever.”
Your hype girl who makes it feel like self-care
“Seven days in a row. You are actually glowing. One more glass and I'm losing it.”
Menstrual, follicular, ovulatory, luteal — your daily goal shifts a few ounces with each phase, automatically. Your cycle data never leaves your phone.
An adaptive schedule learns your last 14 days and pings where you actually drop off. Quiet hours around your sleep, and it goes silent the moment you hit goal.
Eighteen drink types — matcha, sparkling, sports drinks, wine. Coffee and alcohol adjust your effective total instead of pretending they are water.
HealthKit workouts raise your goal on active days, and hot weather adds a boost before you feel it.
Your goal paces itself across the day — steady through the morning, winding down before bed.
Milestones at 3, 7, 14, 30, and 60 days, each with its own celebration — and each one unlocks a new app theme, from Ocean to Midnight Rose.
Log from the Apple Watch app, an interactive widget, or Siri — without opening the app at all.
Take a Day 1 photo, then check in at milestones over 90 days. Everyone's different — but consistency has a way of becoming visible, and it's a lot easier to keep a habit you can see.

Share your storyMost hydration apps were built like fitness trackers — cold, clinical, and clearly not designed with women's health in mind. Hydrate is personal, cycle-aware, and honest about what it takes to make a habit stick. Your health data stays on your device; the only thing we share is enthusiasm.
We built what the others didn't bother to.
