Write
Capture your thoughts, tag your mood, and save a title and body before the moment fades.
Night sky journal for iOS
Your thoughts become stars.
Write before bed. Watch your thoughts become a sky you can explore over weeks, months, years.
Your weeks, mapped
Each week becomes its own constellation — a cluster of stars you can name, connect, and revisit.
A habit that sticks
Gentle reminders, ambient sound, and Face ID lock make journaling feel like a ritual, not a chore.
Your sky, your data
Search past entries, track your streaks, and export everything whenever you want.
How it works
A calm journaling loop with a sky-sized memory.
Nightbook turns each evening check-in into something visible. Write once, then keep revisiting the same sky as your weeks gather into patterns.
Watch it bloom
Each new entry blooms into a glowing star with a gentle pulse, sound effect, and haptic response.
Explore your sky
Swipe through weekly constellations, tap stars to revisit entries, and trace meaning over time.
Built for reflection
The product details stay in service of the ritual.
Weekly clusters, search, stats, reminders, and privacy controls all sit around the same core idea: your writing should feel quiet, immediate, and worth returning to.
A floating capsule bar, frosted week label, and smooth transitions keep the interface feeling unmistakably native on iPhone.
Constellations
Five entries in a week become a constellation in your sky and a milestone in your stats.
Stats & streaks
Track total stars, day streaks, mood distribution, and constellation count at a glance.
Search
Search titles and body text with highlighted matches when you need to revisit a phrase.
Daily reminders
Choose a notification time that fits your evening routine without feeling intrusive.
Face ID lock
Keep private writing private with biometric protection whenever you open the app.
Ambient sound
Layer in subtle night-time sound with simple volume control while you write and browse.
Export / import
Move your sky in and out as JSON whenever you want a portable copy of your journal.
Custom moods
Create your own mood tags using any emoji and any colour that fits the feeling.
Mood colours
Tag each entry with a mood. Your sky reflects how you feel.
Nightbook begins with six default moods and leaves room for custom combinations of emoji and colour whenever your emotional vocabulary grows.

First night
A guided introduction that ends with your first star.
New users are welcomed with a short, calm onboarding: a demo sky to explore, a mood picker, a first entry prompt, and a final moment where the camera drifts towards the newly created star. The whole sequence takes under two minutes. By the end, your sky has its first light.
Welcome and demo sky
"Your thoughts become stars. Your weeks become constellations."
Choose a mood
Pick an emoji and colour that match how you feel tonight. That mood becomes the colour of your first star.
Write your first entry
A gentle prompt to help you begin. No blank page, no pressure — just a few words to close the day.
Sky reveal
The overlay fades, the camera settles, and the first star pulses into place.
Built for night
Dark, quiet, and made for the hours before sleep.
No light mode. No bright screens. Every surface, every transition, every detail is tuned for low light and calm focus. Nightbook feels native on iPhone because it was designed for one moment: the quiet end of your day.
A sky that breathes
The background drifts and shimmers the way a real sky does. Subtle enough to stay in the periphery, alive enough that the app never feels static.
Nothing in your way
Pick your mood, write your entry, watch it bloom. The interface stays out of your way so the focus is always on what you want to say.
