Turn focus into a universe. Stellar is a focus timer that rewards your concentration. Every session you complete creates a real celestial object, stars, planets, nebulae and rare cosmic phenomena, that takes its place in a universe that's entirely your own. Stay focused. Watch your galaxy grow. A FOCUS TIMER THAT MEANS SOMETHING Set a session, put your phone down, and stay on task. Finish, and you'll discover a new celestial body, the longer and more consistent you are, the rarer your discoveries. BUILD YOUR OWN UNIVERSE Pan and zoom across a living star map. Your discoveries form constellations, drift with subtle parallax, and glow against deep-space nebulae. No two universes look alike. COLLECT THE COSMOS Fill your Codex with 60+ celestial types across stars, planets, nebulae, and cosmic phenomena, from common yellow stars to mythic discoveries. STAY CONSISTENT Daily missions, focus streaks, and level progression keep you coming back. Watch your universe expand session after session. COSMIC SHIELD Block distracting apps during a session so nothing pulls you off course. Beautifully designed, calm, and rewarding. Stellar makes deep work something you look forward to.
