Staying hydrated is easier with a little company. Waifu Hydration is a water tracker and reminder with a pixel-art waifu who drinks along with you: tap Give water and she takes a sip and thanks you, tap her and she blushes~

TRACK YOUR WATER
• Log a glass with one tap, fix mistakes with − and +
• Set a daily goal from 1 to 20 glasses
• Watch the ring fill up as you get closer to your goal
• See your week at a glance, with a goal line on the chart
• Forgot a glass last night? Fix yesterday's count; older days stay locked (no sneaky edits, she checks)
• A Today button brings you back from any day

REMINDERS THAT FIT YOUR DAY
• Specific times: pick the exact times you want a reminder
• Every X minutes: from every 15 minutes up to every 12 hours
• Quiet hours: no reminders while you sleep
• Later: snooze any reminder for 10, 15, 30 or 60 minutes
• Precise timing (optional): reminders arrive on the minute
• Reminders keep working when the app is closed, after a restart, and when you travel to another time zone

HOME-SCREEN WIDGET
• Her face and today's progress on your home screen, in three sizes
• The bar turns green when you reach your goal

WAIFU HYDRATION PRO
One purchase, yours to keep:
• Three more waifus: Midori the tomboy, Mitsu the sweetheart and Yoru the catgirl, each with her own voice. Pick one in Settings and she hops over from Google Play (about 6 MB), then stays with you, even offline
• No ads: the banner goes away and the ads software doesn't run at all
• Give water straight from a reminder, with Undo, without opening the app
• A one-tap Give water button on the widget
Tracking, reminders, the widget and Shizuku, your first waifu, never need Pro.

YOUR LOOK
• Light or dark, or follow your phone's setting

PRIVACY
• No account and no sign-in
• Your log and settings are stored on your phone (Android's own backup can copy them to your Google account)
• Tracking and reminders work offline
• One small banner ad from Google without Pro; the privacy policy explains what it collects
• Extra waifus come from Google Play, only when you pick one

Waifu Hydration is a friendly reminder app, not medical advice. Ask a doctor about how much water is right for you.
