Beiwo · 睡了么

A social sleep habit app where friends virtually crawl into the same Beiwo. Seeing who is already in bed turns wind-down into a shared, playful ritual.

The Problem

Bedtime is the loneliest
part of the day

Existing sleep apps focus entirely on individual optimization — tracking, scoring, nudging. They treat sleep as a performance metric rather than a human experience. Meanwhile, the social rituals around bedtime — saying goodnight, knowing your friends are winding down too — have no digital equivalent.

📊
Sleep apps are transactional
You open them alone, get a score, close them. There's no warmth, no community — just data about your failure to sleep well.
💬
Social accountability is missing
We know habits stick better with friends — exercise, diet, study. But nobody has applied this to sleep, where the stakes are just as high.
🌑
Doomscrolling fills the void
Without a ritual or social signal to end the day, the path of least resistance is the phone — which makes everything worse.
🛌
"Just five more
minutes…"
The universal bedtime struggle — no accountability, no ritual, no gentle nudge from the people you care about.
The Core Insight
Seeing a friend already in bed doesn't make you feel pressured — it makes you feel invited.
Research finding from user interviews · Early 2025

The mechanic is simple: when a friend joins their Beiwo (crawls in), you get a soft notification. Not a push to perform, but a quiet signal that the people you care about are winding down. It transforms bedtime from a solitary obligation into a shared, cozy ritual.

How It Works

Three moments
that matter

01
🪺
Create a Nest
Name your Beiwo, set a sleep goal, and invite friends. The setup is playful and low-friction — done in under a minute.
02
🌙
Wind Down Together
As friends crawl in, you get a gentle notification on your lock screen. Seeing the avatars fill up makes putting the phone down feel earned, not forced.
03
☀️
Morning Rise Recap
Wake up to a playful leaderboard — who slept earliest, who slept longest. Friendly competition that celebrates rest, not hustle.

Reflection

What I'm learning

🎯
Designing for emotion, not metrics
The hardest design challenge was resisting the urge to add sleep scores and analytics. Beiwo's power is in its warmth — numbers would kill the vibe.
🔔
Notification design as core UX
The lock screen notification is the most important screen in the entire app. Getting the tone right — gentle, inviting, never pushy — was weeks of iteration.
🌱
Social mechanics need trust
Features like "who's still awake" require careful privacy defaults. The opt-in architecture had to feel safe before it could feel fun.
