Our Story
Built for couples.
Not just individuals.
Every sleep app we tried tracked one person in isolation. But sleep — especially for couples — is anything but isolated.
The problem we kept running into
We noticed something that every couple who shares a bed quietly knows: your sleep and your partner's sleep are deeply connected. When one person tosses and turns, the other pays for it. When your bedtimes drift apart by an hour, the relationship subtly suffers. When you finally sync up on a good night, the morning feels different.
The research backs this up — sleep compatibility is one of the least talked-about but most impactful factors in relationship quality. Yet every sleep tracking app treated each person as if they slept alone on a desert island.
We wanted a number. Something simple that told us, each morning: how in sync were we last night? That number didn't exist. So we built it.
What SleepTwo does
SleepTwo automatically tracks both partners' sleep — using your iPhone microphone or Apple Watch, with no logging, no buttons, no friction. Each morning it computes a "compatibility score" (0–100) that captures how in sync you slept: your bedtime alignment, how much your restlessness crossed over, and how your heart rate variability patterns compared.
It also does the small things that matter: letting you send a goodnight message to your partner's lock screen even when you go to bed at different times, tracking your sleep streak together as a couple, and surfacing insights about your shared sleep patterns over time.
No manual logging
Life is too short to tap buttons before bed. Your iPhone mic or Apple Watch handles everything automatically.
Both partners, one lens
Individual sleep metrics miss the point for couples. Every feature is designed with both of you in mind.
Privacy first
Your sleep data lives in your personal iCloud (CloudKit). We never sell it or use it for advertising.
Our mission
Help couples sleep better — together.
Because the way you sleep next to someone shapes the relationship you build with them. And you deserve data that reflects that.
