All you press
is Start.
An app for sleeping to
readings and night sounds.

ONE BUTTON AT NIGHT

At night, all you do
is press Start.

So that there is nothing to choose before bed, the narrator's voice, speed and pitch are set once during setup, and the only thing to do each night is press Start. The narrator is chosen by a three-question “voice reading”.

Press Start and Yoruyomi reads Japanese classics from Aozora Bunko and gentle explanations of sleep research in a voice that is easy to fall asleep to. The reading plays with one of fifteen sounds—forest, sea, rain, starry sky, shoreline, campfire, thunderstorm, river, noise and more—and stops naturally around the time you fall asleep. It keeps playing with the screen locked.

NIGHT SKY / GOLDEN LIGHT

Night and morning,
in the same quiet world.

The icon and screens share a deep indigo night sky and golden light. In the morning, sleep records from Apple Watch and Health become a score and graphs showing deep sleep, REM, awakenings and daily rhythm. Tell a dream you remember and it becomes text, a scene-by-scene script and a short film.

ON THIS IPHONE

Health records stay
on this iPhone.

Sleep records from Apple Watch and Health are only read, never written. All sleep analysis happens on the device and nothing is sent to our servers.

For the sounds in the bedroom at night, only their type and loudness are recorded once a minute; the audio itself is never saved. Permissions for alarms, notifications, Health, calendar, microphone and more are requested one at a time during setup, each with its reason.

Yoruyomi is not a medical device and is not intended to diagnose or treat any condition.

BUILD / TEST / REVIEW / IMPROVE

Daily fixes tested,
reviewed, then released.

During development, TestFlight carried two separate apps—the App Store version and a development version for trying each day's fixes—installed side by side on the iPhone. Feedback from App Store review was addressed by reworking the screens shown before each permission request.

Improvements continue: the time from pressing Start to the first words is shorter, the reading keeps playing with the screen locked, and there are more scenes, sounds and alarm tones.

OFFICIAL SITE / INSTAGRAM

An entrance and a connection
beyond the app.

The official site (yoruyomi.aiconication.com) introduces what the app does and has a feedback box that has been open since before release. The privacy policy and support pages live on this site. Development and release news is shared on Instagram (@aiconication_2).
