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.

Your battery drains faster than it recharges. If you're tired of staring at overwhelming task lists and feeling like you are falling behind, Kibo is here to catch you. Backed by Spoon Theory, expressive psychology, and research on neurodivergent burnout, we designed a low-demand self-care system to help you clear your mind and find peace, even on your hardest days. No toxic productivity or red notification badges. Just pure psychological safety and scientifically grounded habits. Key Features: • The Dopamine Menu: Decision fatigue is a real psychological hurdle. Instead of a blank to-do list, Kibo auto-generates a daily Dopamine Menu of quick Starters, heavy Mains, and passive Sides. We do the heavy mental lifting so you don't have to. • Honest Energy Tracking: Validate your exhaustion. Tell Kibo how many "Spoons" you have today, and we will dynamically adjust your Dopamine Menu to match exactly what you can handle. 1-Spoon days mean zero heavy lifting. • Build Your Sanctuary: Behavioral science shows that effort deserves immediate comfort. Earn Kibo Coins for completing your menu—whether that's hydrating, resting, or deep cleaning. Spend them to unlock soft, isometric decor for your digital room. • Grounding Exercises: Have a heavy day? Use our tactile Vent tool to physically bury your negative thoughts in the soil and watch the tension dissipate—a digital exercise in emotional regulation. • The Memory Shelf: Keep the good days safe. Store your daily joys on a beautiful wooden shelf. Whenever your battery is low, open a jar to remind yourself that you are doing better than you think. Why Kibo? • Because self-care shouldn't feel like a chore. Built on behavioral science, Kibo doesn't punish you for skipping days or breaking streaks. We celebrate your gentle effort, prevent overexertion on high-energy days, and protect your peace of mind. Trade heavy burdens for a soft landing. Download Kibo today and take a breath.
