Most people I know have installed a water tracker at some point and quit within a week. I tried to fix that in Hydrolotl with a pet that depends on your drinks and no penalty for a missed day.
Curious what's worked for you: reminders, streaks, widgets, something else?
Hydrolotl is a water tracker for iPhone, iPad and Apple Watch where every drink you log fills a pet axolotl's tank. Steady drinking makes its gills bloom and turns bubbles into pearls; on goal days it lays eggs that hatch into 22 colour morphs. Log from widgets, Siri or your wrist. Works with Apple Health and iCloud; no ads, no tracking, no account.
