Say hello to your otter: the companion who makes drinking water feel like something you actually want to do. Lutra turns hydration into a habit you keep, not a chore you dread. No spreadsheets, no guilt, just a friendly otter who reflects your progress back at you, one glass at a time. WHY YOU'LL LIKE IT • Log in one tap. Match your quick-add cups to the drinkware you actually use: bottle, mug, or glass, each with its own size. Tap your 20oz bottle instead of typing a number every time. • Your daily companion. Watch your otter shift from sleepy to bright and relaxed as you get closer to your goal. Its ring shows exactly where you stand, at a glance. • Reminders that fit your day. Gentle nudges keep you on track without nagging. • Home Screen widgets. See today's progress and log a drink without even opening the app. • Medals worth chasing. Forty medals reward first drinks, hot streaks, and hydration milestones. Small wins that add up. • Every drink counts. Coffee, tea, juice, sports drinks: dozens of drink types with Pro, each weighted for how much they actually hydrate you. • Synced privately. Your history backs up to your own iCloud and follows you automatically. GETTING STARTED IS FREE Set your goal, log your drinks, get reminders, use the Home Screen widgets, and earn medals, all free, with 7 days of history to look back on.
