WaterVamp: Hydration Tracker

Stay hydrated. Stay immortal. WaterVamp is a water reminder and hydration tracker wrapped around a chaotic little vampire who thinks water is blood — and keeps you drinking anyway.

YOUR DAILY BLOOD RITUAL

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

- Quick-add: +100 ml / +250 ml / +500 ml
