Get a personalized daily water goal based on your body, track every sip, and see how you stack up against your friends. SMART DAILY GOALS Your water target is calculated using evidence-based hydration formulas that factor in your height, weight, age, gender, and activity level — adjusted for plain water, since you're also getting hydration from food and other drinks. TRACK WATER YOUR WAY Log water with customizable quick-add buttons on your iPhone, Apple Watch, home screen widgets, or lock screen widgets. Long press any button to set your own amount. Ask Siri to log water for you, or use Shortcuts to build your own hydration automations. COMPETE WITH FRIENDS Add friends, climb the daily leaderboard, and get notified when someone passes you. See who hits their goal first, track rank changes in real time, and keep each other accountable. HYDROLEAGUES Create or join leagues with up to 50 members. Invite friends directly — no codes needed. Launch team challenges with four unique game modes and see which team drinks the most. ACHIEVEMENTS & MILESTONES Unlock 18 achievements across four categories: Hydration, Streaks, Social, and Volume Milestones. Build daily streaks up to a full year, and celebrate milestones like filling a fish tank, a bathtub, or an entire swimming pool with your lifetime water intake. Confetti included. APPLE WATCH APP A full companion app for your wrist. See your progress ring, tap to add water with customizable buttons, and sync everything back to your iPhone instantly. WIDGETS EVERYWHERE Small and medium home screen widgets with quick-add buttons. Lock screen widgets in circular, rectangular, and inline styles. Your progress is always one glance away. LIVE ACTIVITY & DYNAMIC ISLAND Track your hydration progress right on your lock screen and Dynamic Island throughout the day, updating in real time as you drink. APPLE HEALTH Optionally sync your water intake to Apple Health so all your health data lives in one place. DETAILED STATS View your daily intake over 7, 14, or 30 days with color-coded charts. See your lifetime total in ounces, gallons, and bathtubs filled. Track your best day, daily average, and days you hit your goal. SMART REMINDERS Gentle hydration reminders throughout the day that automatically quiet down after you've logged a drink. No nagging. CUSTOMIZATION Personalize your water container with custom shapes, colors, and visual effects. Watch your water level rise with a physics-based wave animation that responds to your phone's movement.

Verdict
The clearest difference is monetization model: HydroHeros at freemium against Zobi's subscription. HydroHeros also leads on review sentiment (100% vs 75%) and rating (5.0 vs 4.8). Zobi's advantage is ratings volume (26 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.
