Remembering to drink water is hard. But when you can see that your friend is 400ml ahead of you on today's leaderboard? You reach for your bottle without thinking. Suu's social league system puts that friendly pressure inside the same app that tracks your water, meals and workouts.
π
Hydration Meets Friendly Competition
Popular water trackers like WaterMinder, Hydro Coach, Plant Nanny, and Daily Water focus mainly on individual tracking. Suu adds a free weekly friend leaderboard with nudges β plus private leagues with Premium β so drinking water becomes something you do together.
Why Social Accountability Works
Behavioural science consistently shows that people maintain healthy habits far more reliably when they have social visibility and competition. A solo "I should drink more water" decision is a weak motivator. But "my friend is already ahead of me today" is an immediate behavioural trigger.
This mechanism β social accountability β has been shown to increase goal attainment rates by up to 65% compared to private goals[1]. When your progress is visible to others, you perform. When you can see others' progress, you compete. Suu builds this into your daily water goal.

How Suu's League System Works
Suu's social side has two layers: the weekly friend leaderboard with nudges, which is free, and private friend leagues, which come with Suu Premium.
π₯
Weekly Leaderboard Setup
Add up to 4 friends on a free account by username or QR code scan. The season runs MondayβSunday and resets automatically each week.
π
Live Leaderboard
Real-time rankings show: total water consumed, goal completion percentage, and streak score. Updates the moment anyone logs a drink.
ποΈ
Friend Progress View
See your friend's daily water intake, goal completion %, and how many days of streak they're on β if they have sharing enabled.
π
Hydration Nudges
Send a "Let's drink together today!" push notification to any friend. One tap, instant delivery to their phone.
π₯
Season Winner
At the end of each week, the top scorer is crowned league champion. Badges and achievement rewards are unlocked.
π±
Cross-Platform
iOS and Android users compete in the same league. Platform doesn't matter β only hydration does.
Friend Tracking & Nudge Notifications
Even without a private league, you can add friends β up to 4 on a free account β and follow their hydration journey. If a friend has sharing enabled, you can see:
- Their daily water consumption and how much remains to hit their goal
- Their current streak (consecutive days hitting goal)
- Weekly goal completion percentage
- Their hydration score (0β100 performance index)
The "Let's Drink Together" Nudge
If you notice a friend has barely had any water today, one tap sends them a push notification: "Let's drink together today!" It arrives instantly on their phone. Social pressure works both ways β pushing them makes you pick up your own bottle too. And because the reminder comes from a friend rather than a timer, it's much harder to ignore.

Frequently Asked Questions
Is the league system free?
Partly. The weekly friend leaderboard and hydration nudges are part of the free tier, and a free account can add up to 4 friends. Creating or joining a private friend league requires Suu Premium.
My friend has an iPhone, I have Android β can we be in the same league?
Yes. Suu supports cross-platform leagues. iOS and Android users can compete in the same weekly league.
How many friends can join my weekly leaderboard?
A free account can add up to 4 friends, and all of them appear with you on the weekly leaderboard. A small group keeps competition tight and the leaderboard easy to read at a glance.
Will my friend see exactly how much I've drunk?
Only if you have sharing enabled in your privacy settings. You control exactly what others can see. You can share full progress or just your league ranking.
What makes Suu different from WaterMinder or Hydro Coach?
WaterMinder and Hydro Coach focus mainly on individual tracking. Suu adds a social layer: a free weekly friend leaderboard, hydration nudges, friend progress tracking, cross-platform competition between iOS and Android, and private friend leagues with Premium. It also offers iOS Dynamic Island support and, with Premium, the full 91-drink list with hydration factors and PDF hydration reports.
