Sip Up

A water-tracking app built around the way people actually drink — by brand and bottle size — with a social layer that makes hitting your daily goal genuinely competitive.

The Problem

Most Americans are dehydrated.
Existing apps haven't fixed it.

Hydration apps exist, but they're not enough. They ask you to enter ounces manually, track generic cups, and check in alone. They solve tracking, not motivation. Users want fun, one-tap options. Sip Up is built around how people actually drink water in 2026: by their Stanleys, Hydro Flasks, and Yetis.

Core Concept

Log how you actually drink.

💧
Bottle-first logging
Select your bottle brand and size — Stanley 40oz, Hydro Flask 32oz, Yeti 30oz — and log with one tap. No mental math, no manual entry.
🔥
Streaks & XP
Hit your daily goal and build a streak. Earn XP, level up, and unlock badges. Missing a day stings just enough to keep you honest.
🏆
Social competition
Challenge friends to hydration contests. Follow each other's logs in a real-time activity feed. Turn a solo health habit into a shared game.

The Social Edge

The most effective habit tool
is other people.

Behavioral research is unambiguous: social accountability and friendly competition are among the most reliable mechanisms for sustaining new habits. Sip Up is engineered around this — the social layer isn't a feature, it's the product.

Why Supabase for social?

Supabase Realtime lets friend activity feed updates push instantly without polling — critical for making the social layer feel alive. Row-level security handles the friend graph access patterns cleanly, and the Postgres foundation means complex leaderboard queries stay fast as the user base grows.

Status

Prototype stage.

Core home screen, bottle-first logging flow, and streak system are designed and prototyped. Currently working through the social graph architecture and the real-time challenge system. iOS build targeting for TestFlight in the coming months.
