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.

Focus from departure to arrival. Pomorail turns a metro ride into focus time. Pick your destination and the ride sets how long you'll focus. While a 3D train runs along the real tracks, give your attention to one thing. When the train arrives, your session is done. ■ How a ride works - Pick a route: choose a departure and an arrival on the metros and railways of Korea, Japan and Taiwan, and the ride sets your focus time. - Suggested routes: from 25 minutes to 3 hours, get routes that match the focus time you want. Star the trips you take often. - Seat and task: take a seat and choose what you'll do: work, study, reading, coding or writing. You can add your own. - Ticket and gate: slide your ticket through the gate, the doors close, and the train departs. ■ Built to protect your focus - A 3D train on real tracks: it runs over satellite imagery along the actual lines and changes lines at transfer stations. - 3D cities: download a country's 3D city, with its buildings and landmarks, and ride through it. - Train sounds: departure, running and braking sounds, with doors and city sounds in the seat view. They play even in silent mode. - Distracting apps stay parked: the apps you choose are locked during the ride and released on arrival (Screen Time). - Lock Screen and Dynamic Island: see the time left and the stretch you're on without opening the app. - Home Screen widgets: book a favorite ticket in one tap and follow the train in service. - Arrival alerts: we'll let you know when you reach your stop. ■ Your record grows - Every finished ride becomes a ticket, and your completed rides and total focus time add up at a glance. ■ Your data stays on your device - No sign-up and no location access. - Your ride history is stored only on this device. Anonymous usage statistics that help improve the app can be turned off in Settings. - No ads. ■ Made for you if - Pomodoro timers felt too rigid - You need a nudge to start studying or working - You love subways and trains - You want to put your phone down and focus on one thing Available in Korean, English, Traditional Chinese and Japanese. ※ Ride times are estimates from distances between stations plus stop and transfer times.
