THE PROBLEM NOBODY NAMES
By the time you're finally in bed, you've made hundreds of small decisions since the morning. What to wear, what to answer, what to worry about. Your brain isn't tired — it's full.
So you reach for your phone, hoping something will help you fall asleep.
Instead, you're asked to choose again.
Rain or waves?
A story or music?
Ten minutes or forty?
One more tap..
One more scroll....
One more decision...
Sleep shouldn't be one more thing to figure out.
THE WHOLE APP, IN ONE BUTTON
One button. No browsing, no decision fatigue, no twenty minutes lost hunting for the "right" sound while you get more awake by the second. Press Simmer, and it plays what actually helps you fall asleep — learned from your nights, tuned to your taste, ready the moment you need it.
You don't choose. You don't search. You close your eyes.
Press one button. Simmer quietly takes care of the rest.
Answer a few simple questions, and your very first session is already yours.
Every night teaches Simmer a little more about what helps you drift off.
SLEEP TOGETHER
Some people say goodnight across the room.
Others across the world.
With Simmer, the same gentle night begins in both places.
The same rain.
The same story.
The same quiet moment before sleep.
No calls.
No video.
No pressure to stay awake for each other.
Just the comfort of knowing someone you care about is falling asleep beneath the same stars.
On your nightstand, a small star glows quietly beside your own.
Far away, another one glows beside theirs.
The same sounds fill both rooms.
The same peaceful silence follows.
When they fall asleep, their light gently settles.
You smile.
Close your eyes.
And let the night carry you both.
No chat. No video. No streaks. No pressure to stay awake for each other. Just two people sharing the same quiet night.
Simmer Plus · free to try during your first 7 nightsHOWEVER TONIGHT FEELS
Most nights, you'll simply press Simmer. But some nights call for rain against a window. A favorite story. A sound you've made your own. However you like to fall asleep, it's waiting for you.
01
Most nights, this is all you'll ever use.
One press.
No searching.
No playlists.
No deciding.
Just a gentle night, chosen for you.
02
Some nights, you know exactly what you're in the mood for.
A quiet story.
Gentle piano.
Rain on a rooftop.
A forest at dusk.
Explore whenever you like. Or simply press Simmer and let it choose.
03
Some sounds belong together.
Rain with distant thunder.
Ocean waves beneath soft wind.
Create your own combinations, save them, and they're always ready when you are.
04
When sleep deserves a little more intention.
Pair a story with gentle rain.
A meditation with the ocean.
Soft music that lingers long after the narration ends.
Set your timer. Dim the lights. Let the room settle around you.
THE WHOLE WORLD, TO SLEEP TO
Rain against the window.
Waves beneath the moon.
A quiet forest after dusk.
The gentle crackle of a distant storm.
Some nights, you already know what helps you drift off. Most nights, Simmer quietly knows for you.
NATURAL ELEMENTS
Every place has its own silence. Rain · Ocean · Forest · Wind · Streams · Thunder · Caves · Crickets · Birdsong · City nights · Brown noise · …and many more waiting for the nights you need them.
SLEEP MUSIC
Music written for letting go. Soft piano. Warm textures. Slow, unresolved harmonies that never ask your mind to keep listening. Only to let go.
CALM, SPOKEN
Sometimes the quietest thing you can hear is another human voice. Gentle bedtime stories. Sleep meditations. Breathing exercises. Softly spoken, never rushed, always inviting you a little closer to sleep.
ENDLESS
Some sounds shouldn't end. Loop your favorites all night. Or only until your sleep timer fades them away. No interruptions. No restarting. No midnight surprises.
There are thousands of peaceful nights waiting inside Simmer. The beautiful part is… you'll rarely have to look for them. Just press the button. We'll take it from there.
ONE PRESS, THE WHOLE ROOM
One press, and everything settles into place. The lights soften. Your favorite sounds begin. The room grows quieter. Warmer. Calmer. By the time you close your eyes, bedtime has already begun.
Connect your favorite Google Home or Apple Home scenes, and every ritual becomes more than something you hear. It becomes something you step into.
Runs entirely on your device. Simmer never sees your home, your rooms, or your scenes. Only you do. (Simmer Plus)
ALWAYS LEARNING · ALWAYS YOURS
Every night teaches Simmer something new. The sounds that help you drift off. The rituals you return to. The moments that quietly become part of your evening. Connect your Apple Watch or Android wearable, and Simmer learns from what actually happens — not just what you think you like, but what genuinely helps you fall asleep. Little by little, every night becomes a little more yours.
Your sleep belongs to you. Always.It's never sold. Never shared. Never used to advertise. Delete your history, your recommendations, or your account whenever you choose. Some things should remain personal. Sleep is one of them.
