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.

Pick a timer. Decorate it. Focus. Pochi is a focus timer you decorate with stickers. When the timer on your screen is one you made cute yourself, it's a little easier to stay with your work. ■ Pick your timer Dial, Donut, Moon, Flower, Berry Milk, Heart, Stars, Hourglass, Candle, Cat, Flip, and Big Numbers. Each of the 12 timers shows time passing in its own way. Choose 15, 25, 45, or 50 minutes, or set any time you like. Flip and Big Numbers fill the whole screen — perfect for study-with-me videos. ■ Decorate it with stickers Place stickers on your timer board, then move, resize, and rotate them however you like. 94 stickers: animals, snacks, plants, weather, stationery, study, and feelings, plus hand-drawn crayon sets for exams and celebrations. You can also change the background, main color, paper (Plain, Grid, Dot, Check, Cork, Lined), and border (Clean, Crayon, Colored Pencil). ■ Save your looks Everyday, exam week, birthday week… Save a decorated timer as a look and bring it back anytime. ■ Share it as a card Put today's decorated timer, your focus time, and time per tag on a single card. Pick 1:1, 3:4, or 9:16, then share it right away or save it to Photos. You can make a card of this month's calendar, too. ■ Your days fill the calendar Every session you finish lands on that day's calendar. Put stickers on the days, too, and decorate your month. Add to-dos for each day and tap ▶ to start a timer for that tag right away. Leave a one-line note after a session, or add a record you forgot to time. ■ See your progress at a glance How much you focused each day, where your time went, and how consistent you've been — shown as bars, a breakdown by tag, and a 5-week heatmap. ■ Make it yours Add your nickname and your timer's title becomes "Joy's timer". Studying past midnight? Move the start of your day later. You can also keep the screen on while the timer runs. Use Pochi in English or Korean — switch anytime in Settings. ■ Your records stay on your phone No sign-up, no login. Everything is stored only on your device and never sent anywhere.
