Sideria

a living sky for your habits

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Your habits are stars. Show up each day and watch them evolve -- from molecular clouds to pulsars. Build constellations with the people who matter. Sideria turns your daily habits into a living sky. Every habit is a star. Show up for it and it grows --- from a faint cloud of dust into a steady main-sequence star, through red giant and planetary nebula, all the way to a pulsar sweeping its beam across the cosmos. The journey takes months, and there’s no way to rush it. That’s the point. Share a habit with someone and your two stars become a binary, circling each other. Keep showing up together and the orbit tightens. Groups gather into constellations. The sky fills with light one kept promise at a time. Break a long run and your star goes supernova --- one bright moment, then quiet. But nothing is truly lost: start again and it reignites from the remnant, carrying the memory of everything you built. Each habit has a sound, too. Its resonance --- a generative ambient soundscape --- grows out of your own history with it, one voice at a time. The longer you tend a star, the richer it sings. When someone else is tending a habit like yours, you can send them a pulse --- a wordless flare that means “me too, keep going.” A pulse is a single point of light: it carries no message, no image, and no way to reply. It’s encouragement reduced to its kindest atom, passing between two people who may never meet. If it becomes mutual, it can quietly grow into a bond. Everything in Sideria is earned the slow way. The sky runs on a single currency --- days you actually showed up --- so every star, every orbit, every voice in the sound is a true record of your own attention. It celebrates rarely, witnesses faithfully, and gets out of the way so the work stays yours. > Solo, pair, and group habits Real stellar evolution (T Tauri, Cepheid, pulsar --- the works) > Ambient resonance that grows from your consistency > Wordless pulses of encouragement between kindred stars > Building and breaking habits alike (sobriety and recovery included) IN-APP PURCHASE Sideria is free to use. Your sky, the calendar, the journal, the ambient sound, and every stage of stellar evolution are yours without paying --- up to five habits you’re building, and unlimited habits you’re breaking. Sideria Supporter ($36/year) funds the social layer: sending a beacon to start a shared habit, sending pulses, opt-in discovery of kindred rhythms, and more than five building habits at once. Joining is always free. If someone sends you a beacon, you accept it, share their star, and receive their pulses without a subscription --- the sender carries the cost for everyone in their constellation. Habits you’re breaking --- sobriety, recovery --- are never limited and never paywalled. Sideria Supporter is an auto-renewable annual subscription ($36/year). Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Terms of Use (EULA): https://sideria.io/terms Privacy Policy: https://sideria.io/privacy
