Drinking enough water is simple - until life gets in the way. Wotah turns hydration into a small daily ritual with your duck buddy Quackers. Tap a glass. Keep the streak. Stay hydrated with Quackers. WHY WOTAH IS DIFFERENT • Quackers, your friendly duck buddy, cheers you on with every sip • Smart reminders tuned to your day, not a generic schedule • One-tap logging - no math, no menus, no friction • Daily goals, streaks, and confetti moments that make the habit stick • A whole crew to unlock - meet Otto, Axel, Hoppy and more as you grow • Home screen widget so your goal is always one glance away HYDRATE TOGETHER WITH FLOCK Add real friends to your Flock and see each other's daily progress. Send a duck-delivered nudge when a buddy falls behind - and cheer when they hit their goal. It's gentle accountability that makes the habit stick. Flock is optional and private: only your name, buddy, count and streak are shared, and only with friends you add. BUILT FOR REAL LIFE Sign-up optional. No ads. No data harvesting. Track your water with zero setup, or sign in to unlock Flock. Quackers lives quietly on your phone, nudges you when it matters, and gets out of the way when it doesn't. WHAT YOU'LL FEEL Better focus, better skin, better sleep - all from the simplest habit there is. Start small. Stay consistent. Quackers is waiting.
