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.
FREE, WITH AN OPTIONAL PLUS
Everything above is free: every habit, every month, every friend, your export.
Nebula Plus adds one exclusive form for your cosmos each month — and a month
you light with Plus keeps that form for good.
Available in English and Ukrainian.
Nebula Plus is an auto-renewable subscription. Payment is charged to your Apple Account at
confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the
end of the current period; manage or cancel it in your Apple Account settings.

• Faster sync: Nebula now downloads only the months that changed.
• Friend invite links now open right in Nebula.
• A new home on the web: nebulahabits.app
