"I've clearly been busy, but when I look back, there's nothing to show for it." "I don't know how time passes — I just drift through the day." "I reply to a message and end up on social media for an hour... I keep putting things off." There's only one reason time management is hard: you can't see it! Track where and how much time you spend, and reflect on your day. You'll start to see the wasted time you never noticed, how often you switch tasks, and your unconscious behavioral patterns. Timing is based on MBI (Mindfulness-Based Intervention) theory, focusing on paying attention to the present moment and observing your habits without judgment. Instead of forceful screen blocking or group features that create exhausting competition, we designed a healthy, objective way to review your day. It’s all about 'reclaiming your time agency' — spending your time exactly where and how you want. From a day driven by time, to a day driven by you — that's Timing! ■ Effortless Tracking -Start and stop your timer with a single tap. -Easily add, edit, and delete records directly on the grid. ■ Live Activity -Record faster right from your lock screen. -Check your tracked time without even opening the app. ■ Home Screen Widgets -Add Timing's widget to your home screen! -Check your time and start recording directly through the widget. ■ Unlimited Presets -Save your frequently used activities as presets across 3 categories (Focus · Rest · Other). -Start tracking instantly from the home screen using your saved presets. -No limits on presets — customize Timing to fit your exact lifestyle! ■ Daily & Weekly Insights -Timeline view intuitively split into AM and PM. -Cumulative time spent per activity by time slot. -Percentage breakdowns by category and individual activities. -Focus-rest balance analysis. -Weekly heatmaps and time distribution charts by day of the week. ■ Beautiful, Easy-on-the-Eyes Grid -Visualize your day with a grid featuring 5 minutes per cell and 1 hour per row. -A touch of green — the most restful color — adds a stylish flair to your desk setup and daily records! ■ Streak Tracking -Keep your momentum going and break your longest streak record every day!

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
