Starhush: Calm Constellations
Count the stars before sleep
Free · Designed for iPad. Not verified for macOS.
Five quiet minutes before sleep: connect the stars in time with their breathing light. 88 constellations, old stories, calm music and 3D views at real distances.
Spend five quiet minutes before sleep connecting the stars of the night sky, one by one, into a constellation.
Breathe slowly with the starlight
The next star brightens for 4 seconds and dims for 4. Tap it gently when it shines brightest, and your breathing naturally slows and settles. There is no rush and no wrong answer.
A lullaby that grows with every touch
Each star you tap adds a note to a little melody, and the last one rings out in a chord. Calm music, created live by the app, plays softly in the background.
88 constellations and their old stories
All 88 constellations recognized by the International Astronomical Union are here. When you finish one, you read its Greek myth, and how people in old Korea and Japan saw the same stars: the Big Dipper, the Weaver Girl and the Cowherd, Subaru and more.
Turn it and see real distances
Turn a finished constellation with your finger. Every star sits at its real distance from Earth, so stars that look side by side turn out to be hundreds or thousands of light-years apart. Tap any star to see its name and distance.
Tonight's constellation
Starhush picks a constellation that is actually high in tonight's sky. One a night, and each one is kept in My Sky.

No account needed, and your constellations stay on your device. Ads appear only once a night when you start, as a small banner in My Sky, and as an optional ad to connect one more. None while you connect stars or gaze at them. Optional nightly reminders tell you which constellation awaits.
Starhush is made for relaxation and is not a medical device.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
My Sky now opens on the constellation you just collected. Before, it could open on another part of the sky where your constellation was not visible. A constellation is now saved the moment you connect its last star. Sound no longer stops after you plug in or unplug headphones. Star data was corrected, including Cor Caroli in Canes Venatici and Alpha Centauri, and stars with no distance data now show only their name. Chinese constellation names and translations in several languages were polished. If notifications are turned off in iOS Settings, the reminder switch in the app now shows as off. In Europe, the app asks for your ad privacy choice at first launch, and you can change it anytime in Settings. Small buttons are easier to tap, and VoiceOver no longer reads out icon names.
