Nebula: Habit Tracker

About this app

Nebula is a habit tracker where every completion lights a star. Check off a habit and a new star ignites in this month's cosmos. Hold the rhythm and the month becomes a celestial object of its own, kept in your collection for good. Year after year those objects grow into a galaxy that is only yours. ONE SCREEN A DAY Today's habits and a couple of taps to close them. Streaks, progress, gentle reminders at your hour. No feed, no ads, no endless settings. A COSMOS THAT GROWS WITH YOU Every month is drawn from your own data: the steadier the habits, the richer the object. A nebula, a binary star, a ringed world — all of it breathes, and none of it repeats. A MISSED DAY ERASES NOTHING Skip a day and the light simply dims. No red failure badges, no counters reset to zero: what you have built stays built. FRIENDS ALONGSIDE Add friends and watch their universes grow. Share your cosmos as a single image. Your profile is private by default — you decide what to show. YOUR DATA IS YOURS Export everything as JSON and delete your account outright, right in Settings. No ads, and we never sell your data. Nebula is free. Available in English and Ukrainian.

Smoother cosmos, calmer celebrations. • Your cosmos now fades in instead of appearing all at once. No more dark pause on a cold start. • The first-star moment is quieter. The star you just earned lights up in your own sky, with no extra flourish on top of it. • Reminder time ticks gently as you scroll through the hours, and the button now says exactly what it will set. • Fixed: reopening the reminder time picker right after closing it could save an hour you had discarded. • Wording and layout touch-ups on the sign-in and home screens.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
