iLuma is a productivity and focus app that turns your daily planning and study sessions into an immersive, rewarding experience. Designed to keep you motivated and accountable, iLuma helps you organize your time while building an entire universe through consistent focus. From the moment you open the app, your home page gives you everything you need in one place: a calendar to plan out your days, a to-do list to track what you need to accomplish, a completed list to reflect on your progress, and a sun tracker at the bottom of the screen where each of the seven suns represents a day of the week and lights up as you complete study sessions. iLuma makes focus feel meaningful by turning it into a game. You can choose from 52 different planets, each representing a focus journey. With Flexible Mode, you can leave the app when necessary and continue growing your planet, making it ideal for lighter focus days. With Strict Mode, you must stay inside the app during your study session or your planet will be destroyed, creating a powerful sense of accountability for deep focus moments. As you complete planets, they are added to your own solar system. Complete an entire solar system and you unlock constellations, gradually building a constellation map that visually represents your consistency, discipline, and growth over time. Whether you are studying, planning your week, or building better habits, iLuma turns productivity into something you can see, feel, and build.
