Focus, and a planet forms. Stay until the timer ends and it joins your galaxy. Quit early and it scatters. A pomodoro focus timer that turns your time into worlds. Made with ADHD and restless focus in mind, Planeta gives every study block, homework hour or deep work sprint a reward you can actually see. HOW IT WORKS 1. Pick a session length from 5 to 120 minutes and start the timer. 2. While the clock counts down, your planet's terrain and colors take shape. 3. When time is up, the planet is yours and joins your galaxy. The rule is simple: stay to the end and you keep what you built. Leave early and nothing is left behind. It's an easy way to stick with the pomodoro technique, one session at a time. NO TWO ARE EVER ALIKE Every session generates a new terrain, color palette and set of rings. There are 20 planet types to discover, and no two planets ever come out the same. LONGER FOCUS, RICHER PLANETS Focus for more than 30 minutes and your planet gains an atmosphere. Go past 60 minutes and it gains a ring. Shorter sessions still leave a planet, just without the extra layers. That's a small reason to stay in flow a little longer. YOUR GALAXY The planets you earn settle into star systems. Pan across the map and see which session each planet came from. Your focus history becomes a place you can explore. THE CODEX A record of all 20 planet types that fills in as you discover each one. JOURNAL Every voyage is logged with its length, its tag and its planet. Add a note to any session so you remember what you worked on. It doubles as a simple study tracker for ADHD study habits, exam prep or long work days.

The longer you put your phone down, the deeper your life gets. Start the timer, set your phone down, and sea creatures come to your ocean. From exam prep to digital detox, dive with Sumbi. Sumbi is a study focus timer and digital detox app named after the "sumbisori," the whistling breath of Jeju haenyeo, Korea's legendary free-diving women. Start a dive when you want time away from your phone. While your phone rests, your ocean deepens, and sea creatures come to live in it. Who dives with Sumbi - Students who need a study timer for exams and deep focus - Anyone fighting phone addiction or doomscrolling - People who want to cut screen time and rebuild concentration - ADHD brains that need a gentle, visual reason to stay off the phone - Anyone who just wants to watch a calm ocean and breathe What makes Sumbi different 1. One dive = one focus session. Keep your phone down while the timer runs, and the dive succeeds. If you fail, nobody scolds you. 2. Your focus time becomes an ocean. Successful dives bring creatures from shallow water, deep water, even the abyss. 3. Collect and raise your sea creatures. The more you dive, the wider and deeper your ocean grows. 4. Gift creatures to your dive buddies. Focus is deeper together. 5. No ads, no noise. Sumbi never drags you back with notifications. Coming back is your choice. Study timer, pomodoro, or deep work Pick any length with the dial: a short pomodoro-style session or hours of exam prep. Every dive adds to your daily focus record. When haenyeo divers surface, they release a long whistling breath: "hooo-ee." Your day deserves a breath that deep. Have a good dive. Hoo-ee! Contact: sumbi@niceday.io
