Four women.
One very hydrated you.
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 — or skip the coach and let Dewy keep you company.
Stacy
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.”
Lex
Data-driven, no excuses, all results
“You're at 60% with 4 hours left. Two 12 oz glasses and you hit goal. No excuses.”
Lily
Warm, encouraging, zero pressure
“A little sip now and you're right back on track. You're doing beautifully — no pressure, ever.”
Jade
Your hype girl who makes it feel like self-care
“Seven days in a row. You are actually unstoppable. One more glass and I'm losing it.”
Not your average water app.
Goals that follow your cycle
Menstrual, follicular, ovulatory, luteal — your daily goal shifts a few ounces with each phase, automatically. Your cycle data never leaves your phone.
Reminders that read the room
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.
Every drink, counted honestly
Eighteen drink types — matcha, sparkling, sports drinks, wine. Coffee and alcohol adjust your effective total instead of pretending they are water.
In sync with your body
HealthKit workouts raise your goal on active days, and hot weather adds a boost before you feel it.
A rhythm, not a quota
Your goal paces itself across the day — steady through the morning, winding down before bed.
Streaks worth protecting
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.
On your wrist and home screen
Log from the Apple Watch app, an interactive widget, or Siri — without opening the app at all.
Your ReadsWatch the habit show up.
Take a milestone photo on Day 1, then add one at each milestone over 90 days — alongside a daily Hydration Read. 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 storyBuilt for women who are
chronically dehydrated.
Most 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.
The basics, plus
the parts that matter.
Everything a good water tracker does, and what most of them skip.

Hydration, explained.
How Much Water Should Women Actually Drink Per Day?
The 8-glasses rule is decades old and doesn't account for your body weight, activity level, or cycle. Here's how to calculate your actual daily water goal.
How Your Menstrual Cycle Affects Your Hydration Needs
Your water needs aren't the same every day of the month. Here's how estrogen and progesterone affect your thirst, fluid balance, and daily goal — phase by phase.
Why You're Always Dehydrated (Even When You're Trying)
If you've been 'trying to drink more water' for years with nothing to show for it, this isn't a willpower problem. Here's what's actually going on.
Your body is
