## What is Stelo?

A private night sky that fills itself, one star a day.

Stelo is a slow, ambient stargazing companion. Every night, one to three new stars quietly fall into your personal night sky. Connect them with your finger to draw your own constellations, give them names, and watch a gallery slowly fill over weeks and months.

There is no score. No timer. Nothing to lose. Just a quiet space that asks nothing of you, and gives back a sky that is yours alone.

HOW IT WORKS

• Open the app. New stars from last night pulse gently to greet you.
• Touch a star to begin a constellation. Drag your finger between stars to draw lines. Branches are allowed; loops are allowed; whatever feels right is right.
• Tap save. Name the constellation, or leave it untitled. It joins your gallery.
• Tomorrow, more stars will be waiting.

SPECIAL NIGHTS

The sky knows what day it is. On 24절기 (Korean solar terms), full moons, meteor-shower nights, and your birthday, special stars appear with a label and a warmer color. Catch them in a constellation for keepsake meaning.

THE ALMANAC

Without telling you what to draw, Stelo quietly compares your shapes to all 88 IAU constellations. If you accidentally rediscover Lyra, Orion, or Cassiopeia, a small banner appears: "Looks like Cygnus." Your discoveries gradually unlock the Almanac with mythology and historical notes — no quiz, no pressure.

WIDGETS

Place a small or medium widget on your home screen to keep your latest constellation glowing through the day.

WHAT WE DO NOT DO

• No ads. Ever.
• No in-app purchases in v1.
• No accounts. No sign-up.
• No analytics, no tracking, no SDKs that phone home.
• No leaderboards. No friends. No sharing pressure. No social.
• No push notifications nagging you to come back.

All your stars and constellations live on your device only. We literally cannot see them.

WHO IT IS FOR

• People who like Universe, Alto's Odyssey, Mountain, or any app that asks nothing
• People who keep a one-line journal or use bedtime apps
• People who like astronomy but find sky-map apps overwhelming
• People who play idle games for the slow accumulation, not the optimization

LANGUAGES

English, 한국어, 日本語. Time zones and 24절기 calendar honored locally.

Stelo. The Esperanto word for "star." A night sky you can hold.
