Hello
SimpleDay is a breathing, relaxation and sleep app. Morning, afternoon, evening or night, it suggests one short guided session: the one that fits right now.
Tap a moment: the sky changes, just like in the app.
How it works
Morning, afternoon, evening or night, it suggests one session that fits the moment. Nothing to search for.
Breathe, loosen your neck, listen to the rain, drift back to sleep. Thirty seconds to fifteen minutes, guided all the way.
Every session grows a flower on your hill, and over the days your little world fills in. Skip a day and you lose nothing.
The little world has one job: to make looking after yourself a habit you actually enjoy.
Morning · 5 am – 11 am
Log your night with one tap, without numbers or a smartwatch. Then take a minute to wake up gently.
Day · 11 am – 6 pm
When the pressure builds, one long sigh can be enough. SimpleDay suggests what fits right now.
Evening · 6 pm – 10 pm
The sky darkens as you do. In the evening the app stays dark, even in light mode, so nothing dazzles you before bed.
Night · 10 pm – 5 am
The rain stops on its own. And if you wake at 3 am, the Sleep tab has a way back to sleep, with no bright light.
Try it now
It rises over the hill as you breathe in and sinks as you breathe out. One minute, just like in the app.
Your hill
Over the days, grass comes in, a sapling takes root, a bench appears. No points, no streak to keep: take a break and everything is still there.
0 days with a session
A bare hill, waiting for you.
Drag to move through time.
One session a week is enough to see something new. Ten sessions in a day won’t grow it faster than two. What counts is coming back.
Your week
Monday to Sunday on a single hill: each day with its flowers, each night with its moon, fuller when you slept well. The days ahead stay in the mist. Then a few true words, with no chart and no score.

Sessions
Each one has a single purpose and lives in a single place. You’ll never scroll through four hundred tracks.

Sleep
A two-step ritual that runs on its own, tonight’s real moon, and a way back to sleep when you wake in the night.
Places
The meadow, the night, the ocean, the rain. Each place follows the real time of day, and the moon only shows when it’s actually up.
Turn the sound up, then tap “Listen” on the meadow or the night.
Wind in the grass, fireflies at dusk.
More stars on moonless nights.
Waves, and a path of light on the water.
Soft rain, and rings in the puddles.
The details
A rare line, depending on the hour, the moon’s phase or the season’s shooting stars. We’ll let you find out how.
In the morning: good, so-so or rough. After a rough night, the app keeps things shorter.
What you set down at night comes back to you in the morning. Once you’ve read it, it’s gone.
The rain fades gently over twenty seconds, then stops, at the time you chose.
Only the ones you want, at the time you want. No other notifications, ever.
Give your hill a name, if you feel like it. It shows next to the date.
Our commitments
The night you log in the morning and what you write in the evening never leave your phone.
Open the app, answer three questions at most, and breathe.
Your week is told in words. If it was a quiet one, nothing is asked of you.
The tree follows the seasons, the moon its real phase, and the sun rises and sets at your time: worked out on your phone, without asking where you are.
Designed for VoiceOver, very large text sizes and Reduce Motion.
Each language is written on its own, never translated word for word.
SimpleDay makes no medical promise and does not replace a health professional.

Questions
A mobile app for everyday wellbeing.

All of it in a small illustrated world that follows the real time of day.
No. The little world is there to make the habit pleasant: every session grows a flower, and your hill fills in over time. There’s no score, and you lose nothing if you take a break.
