Store description excerpt
Your habits find their orbit — grown the way real planets are. Kidou turns your habits into a living, hand-grown solar system. Open it and you don't find a dashboard — you find a night sky. The more you show up, the more it grows: worlds are born, drift into orbit, and slowly come to life. ■ Grown the way real planets are Every habit is a celestial body. Each day you keep it, you "turn an orbit," and the body visibly gains mass. As orbits add up, it accretes through the true stages of planet formation: Dust → Pebble → Planetesimal → Protoplanet → Planet Big goals break down into the smallest possible step — start with "just get ready" — and every few days a stage completes, so growth is always something you can see. ■ You choose: advance or stay Every stage-up is an invitation, never automatic. Move to the next stage, or stay here a little longer. Staying is never a penalty. If a stage feels heavy, you can always drift back to an inner orbit, and your record is never lost. ■ A star ignites at your center When your first habit fully grows, the "you" at the center ignites into a star. Each new planet you form lets you evolve its color — amber, blue-white, pure white, violet, crimson, jade. Tap the star for an overview: worlds growing, worlds formed, total orbits, and an observation log of every milestone. ■ Never shaming, never nagging No "failure." No "streak broken." No "missed." Pausing costs you nothing. A habit that lapses simply drifts away like a comet on a long orbit — and it always returns. No red warnings, no nagging notifications, no guilt badges. ■ Scatter your first dust in about 90 seconds Pick from twelve templates or name your own goal, see its five-stage path, choose a color, and take the first step. ■ Home Screen widget Mark today's orbit right from your Home Screen — a calm checklist, one step at a time, without even opening the app. ■ Entirely on your device No account, no login, no cloud, no ads, no tracking. Your data stays on your device, with no network except Apple's purchase processing. ■ Pricing Grow up to three habits for free. A single one-time Planetarium Pass removes the habit limit, so you can grow as many habits as you like. No subscription — you pay once. The price is shown in the app. There is no rush. Your solar system grows by exactly as much as you showed up for today.
