WaterVamp: Hydration Tracker

Stay hydrated. Stay immortal.

WaterVamp is not your typical water tracker.

Forget boring blue apps. Meet your lovable chibi vampire who thinks water is blood - but genuinely wants what's best for you.

YOUR DAILY BLOOD RITUAL

A hydration tracker you'll actually use.

Log your "blood" with one tap. Watch your animated vial fill as your vampire grows stronger. Hit your goal and the castle celebrates.

- Quick-add: +100 ml / +250 ml / +500 ml
- Custom amount - enter any quantity you like
- Animated vial with a hypnotic wave fill effect
- 36 rotating vampire taglines reacting to your hydration level
- Drop animation & haptic feedback on every single log

Your vampire reacts to your hydration.
Ignore it long enough... and it gets thirsty.
