Studien은 외계인 모리와 함께 집중한 시간만큼 행성을 탐사하는 앱입니다. 내가 책상에 앉아 있는 동안, 외계인 모리는 망원경 앞에서 새로운 신호를 기다립니다. 탐사가 끝나면 세상에 없던 행성이 하나 발견되고, 나만의 도감에 기록됩니다. ■ 두 가지 방법으로 탐사합니다 1. 뽀모도로 타이머 25분, 50분, 1시간 30분, 2시간 중 원하는 시간을 선택해 집중합니다. 선택한 시간이 곧 행성의 등급이 되며, 끝까지 집중할수록 더 희귀한 행성을 발견할 수 있습니다. 2. 스톱워치 시간을 정하지 않고 0초부터 자유롭게 기록합니다. 얼마나 집중할지 정하기 어려운 날에 사용하기 좋으며, 25분 이상 집중하면 행성을 발견할 수 있습니다. 어떤 방법을 선택하든 탐사가 끝나면 망원경에 새로운 신호가 도착하고, 행성이 천천히 모습을 드러냅니다. ■ 도감 행성은 별 1개부터 별 4개까지 다양한 등급으로 구성되어 있습니다. 현재 10종의 행성이 준비되어 있으며 앞으로도 계속 추가될 예정입니다. ■ 오늘의 목표 기록 오늘의 목표와 진행률, 시간대별 집중 기록을 확인할 수 있습니다.

Deep Time isn't about locking your phone or obsessing over minutes. It's about one thing: going deep on what actually matters. Set a single mission. Deep Time imprints it on your lock screen, so every time you reach for your phone, you're reminded of what you sat down to do. Not a wall that blocks you — a nudge that pulls you back. HOW IT WORKS • Set your mission — what do you want to go deep on right now? • See it on the lock screen — your mission and timer stay in front of you, even while the screen is on. • Go deep — a calm focus screen keeps you in the moment. • Look back — every session becomes a record of what you focused on, not just how long you resisted. BUILT AROUND ONE HABIT The goal isn't a perfect streak of blocked apps. It's the experience of deep focus, once a day — and the habit that grows from it. Deep Time shows your weekly rhythm and your focus streak, so a single deep session compounds into a practice. WHY DEEP TIME • Imprint, not restriction — your mission lives on the lock screen instead of a block screen. • What you focused on > how long you resisted — sessions are remembered by their content. • A timeline of real work — see every deep session, its depth, and how it went. • Reflect, don't just count — weekly trends and streaks that reward showing up. • Quiet, warm design — soft dark, distraction-free, made for staying in the moment. Start today. One deep session a day is enough to begin. Deep Time — design your healthy focus.
