Description by Katsuhide Leung Written by the developer, not by AppBrain. Click to read.
Finish a focus session, and a star lights up.

Each subject grows its own constellation, and every session you complete builds a night sky that is yours alone. It is a study timer that lets you feel your progress in the sky, not only in numbers.

For exam prep, certification study, university reports and assignments, or daily self-study. Keep sessions short or focus for as long as you like. The time you finish becomes a star.

- One tap to start a 15, 25, 45 or 60 minute session, or set any length from 1 to 180 minutes
- One subject, one constellation. Which constellation appears next is a surprise, and each one fills in as you keep going
- The timer keeps running when you leave the screen, and a notification tells you when it ends
- See weekly and monthly focus time, with a breakdown by subject. Your study log builds itself
- Exam countdown. Your home screen shows how many days remain until your next exam
- Constellation guide. Every constellation you complete is collected in a guide of 36

Your study data, such as subject names and focus history, stays on your device. There are no ads and no tracking across other apps or websites. For how in-app purchases are handled, please see the privacy policy.

Free to use: the default Deep Indigo Night sky and every feature, including the constellation guide and the exam countdown. Starlit+ adds 7 more skies, including Aurora, Moonlit Night, Milky Way and Night Cherry Blossoms, plus 18 Starlit+-only constellations such as Pencil and Cat. Starlit+ comes in three options, and all of them include the same content:
- Yearly (auto-renewing)
- Monthly (auto-renewing)
- One-time purchase (a single payment)

Yearly and monthly plans renew automatically unless canceled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription at any time in Settings > Apple Account > Subscriptions.
