Sharing a bed shouldn’t cost either of you the morning

for couples.
Sleep for Two helps you both sleep better by coordinating your sleep cycles, encouraging healthy sleep habits throughout the day, and making sure sleep interruptions don’t lead to tough mornings.

One minute, sound on.
01 / Why the cycle matters
15 to 60 minutes
That’s how long the fog lasts when an alarm catches you in deep sleep. It’s called sleep inertia, and it doesn’t care how many hours you got.
Sleep runs in cycles of roughly 90 minutes, light to deep and back up. Wake near the end of one and you come up clear. Wake from the deep part and you get the fog. Sharing a bed makes the deep part a lot easier to hit.
The fixed alarm
The groggy hour isn't the late night. It's the alarm.
An alarm set for 6:30 doesn't know your bedtime moved from 10:30 to midnight. Same alarm, different place in the cycle, and now it lands in deep sleep. You blame the hours. It was the timing.
The 1am walk-in, or the baby, or the dog
Whatever wakes you restarts your clock.
Once you're awake, your cycles start over from when you fall back asleep. The alarm you set at 11 is now aimed at the middle of one. Someone does math in the dark, and by morning someone feels like the bad guy.
Two clocks, one bed
Your alarm is their mid-cycle wake.
Two people rarely finish a cycle at the same minute. One alarm for both of you catches someone in the deep part. Two alarms and two sound machines fight. Either way you become each other's worst alarm clock without meaning to.
02 / Coordinate the night
Two alarms. Two clocks.
One bed.
Each of you saves a wake window once. Each night, one tap sets your own alarm at the end of a sleep cycle inside it. Here is one night, both phones, with the times the app itself picks.
How it times it. Estimates, not measurements.
Your bedtime, plus the minutes you usually need to fall asleep (14 by default, yours to change), counted in 90-minute cycles. It picks the latest cycle end inside your window. No wearable, no tracking, nothing listening to you sleep, and you can see every number it used.
Woken in the night? One tap, and the plan catches up.
Re-time starts the count again from that moment, still inside your window. The tap changes the alarm at once, and the screen shows what it replaced: 6:44 is gone, 7:19 is set. No math in the dark, no one to blame.
03 / Keep the promise you made last night
Be the person
who gets up.
You said seven. At seven, the alarm doesn’t take your word for it.
Choose how it lets you off: a sum, a three-second hold, or a photo of something across the house. The toilet, usually. The photo is checked on your phone and never uploaded. Snoozes are rationed, and the app knows when you’ve actually walked away from the bed.
Ring, one tap, quiet.
Tap “I’m on it” and the bell stops while you do the task. It only comes back if the time runs out. Loud is the failure state, not the default, so it wakes you without waking the house.
04 / One room, one sound
Two phones. One
coordinated sound machine.
Two people with two sound apps get two hisses at two volumes. Link your phones and the sound machine runs as one across both nightstands. Three things happen that separate apps can’t do.
No second hiss
The first to fall asleep starts the sound. The second phone stays silent.
In One phone mode, when they come to bed and start their night, their phone sees the room already has a sound and stays quiet instead of adding a second one. One volume, one hush, no clash.
The sound stays in the room
Their mid-night wake-up rings, so their phone leaves. Yours fades the same sound in.
The trigger is the app's own mid-night wake-up: a feed, meds, the potty. The other phone fades in so the room doesn't go silent behind them, and hands it back when they tap Back to sleep.
A forest with your bed at the center
In Both phones mode, the same sound plays from both nightstands, in step.
Deep on both sides, or a place: rain, a forest, a shore. In Forest the birdsong crosses from your side to theirs, the crickets settle around you, and the room feels bigger than two phones.
Close your eyes. Be somewhere else.
Birdsong crosses the room. Wind and crickets surround you.
A world around you. Just two phones on two nightstands.
Brown · Deep · Pink · White · Rain · Forest · Shore05 / Habits, all day
Good sleep starts
at breakfast.
Your day, laid out from your bedtime backwards.
The Today timeline makes space for a last coffee, a last drink, screens down, and time to unwind, all aimed at the bedtime you chose. Log coffee or alcohol in a tap and look back alongside how your mornings felt.
Get it out of your head.
Tomorrow’s to-do. The thought that keeps coming back. Put it in your private bedtime journal and leave it there for the night. It stays on your phone.
Small habits. A place to keep them.
06 / Someone in your corner
Say “I’m here”
without a sound.
One of you is turning in. The other has another chapter left. Send a little “sleep well,” “I’ll be quiet,” or “I’m here.”
At night they arrive silently: no sound, no buzz, the screen stays dark. It’s there when they look. Each week you also see one kind sentence about how they slept, and they see one about you. Never a chart.
Try it togetherA few things to know
Before the
lights go out.
Is it really the first sleep assistant for couples?
There are couples sleep trackers, long-distance couple alarms, and a smart mattress for two. There has been no app that gives each partner their own cycle-timed alarm, re-times it when the night is interrupted, and runs one sound machine across two phones. That is what we mean by assistant, and that is what's first.
Why not just keep my usual alarm?
If you must be up at 8:00 sharp every day, keep it; this app has an exact-time mode for those mornings. If your bedtime moves and your morning has some give, a fixed alarm lands in the middle of a sleep cycle most days. This one picks the cycle end that fits.
Does it track my sleep?
No. It estimates from your bedtime, your usual minutes to fall asleep, and 90-minute cycles. Nothing listens, nothing is measured, and you can see and change every number it uses.
When can we try it?
Request a beta invitation. We'll email you when your invitation is ready.
Do we both need the app?
Your alarm, wake gate, timeline, and journal work on their own. For shared sound and the goodnights, you'll each need the app on your iPhone. One subscription covers both of you.
How do the two phones play together?
Link your iPhones and place one on each nightstand. In One phone mode the first to fall asleep leads and the other phone stays silent, taking over only if they get up. In Both phones mode the same sound plays from both sides, and in Forest the birdsong crosses between them.
Is my journal private?
Yes. Your bedtime notes, drink entries, and morning check-ins stay on your phone. They aren't shared with your partner.
Do I need a watch or a wearable?
Just your iPhone, running iOS 18 or later. The most reliable alarms use Apple's alarm system on iOS 26.
