집중이 필요할 때, 클라크. 공부해야 하는데 자꾸 흐름이 끊기는 사람? 이제 앉기만 하세요. 나머지는 클라크가 할게요. # 클라크 3.0, 완전히 새로워졌어요 ■ 앉기만 하면 공부가 기록돼요 버튼 누를 필요 없어요. 다이얼을 ECO나 LIVE로 돌리고 앉으면, 카메라가 공부하는 모습을 알아보고 집중한 시간만 자동으로 기록해요. 자리를 비우면 알아서 멈추고, 돌아오면 다시 이어서. 공부 측정 영상은 기기 안에서만 처리되고 서버로 보내지 않아요. ■ 공부할수록 휴식이 충전돼요 5분 공부할 때마다 휴식 1분이 쌓여요. (최대 20분) 잠깐 자리를 비워도 휴식 안에 돌아오면 연속 공부 기록이 그대로 이어져요. 공부할 땐 빡세게, 쉴 땐 마음 편하게. ■ 브리핑: 프린트를 찍으면 AI가 정리해요 (NEW) 학교·학원 프린트, 이제 옮겨 적지 마세요. 사진 한 번이면 AI가 글·표·그림·수식까지 읽어서 공부하기 좋은 개념으로 정리해 줘요. · 버스 안 15분, 이어폰만 꽂으세요. 정리한 개념을 읽어 주고, 끝까지 들은 개념은 공부한 것으로 체크돼요. · 시험 전날, 약한 곳만 다시. 개념마다 확인 문제를 풀고, 틀린 곳은 원문 근거와 함께 다시 봐요. ■ 실전처럼 시험을 연습해요 실제 시험 시간표 그대로 시계가 흘러가요. 절반 경과, 마킹 시작, 종료 1분 전을 화면과 진동으로 알려 주고, 한 문제에 몇 분 써도 되는지까지 계산해 줘요. ■ 공부한 날이 쌓여 보여요 날짜별 기록과 공부 잔디로 꾸준함이 한눈에. 공부하는 모습은 타임랩스로 남아, 내가 얼마나 집중했는지 눈으로 보여요. ■ 인터넷 없이도 OK 공부 측정·기록·시험 타이머는 와이파이 없는 독서실·스터디 카페에서도 그대로. (브리핑의 AI 정리와 듣기는 인터넷 연결이 필요해요.) ■ 켜 두기만 해도 집중되는 화면 레트로 라디오에서 영감을 받은 다크 디자인. 공부를 방해하지 않고, 켜 두는 것만으로도 괜히 집중돼요. 오늘부터 클라크로 공부 시간을 진짜 '내 시간'으로 만들어 보세요. 기록하면 달라집니다. 집중은, 습관이 됩니다.

It's 11pm again, and you couldn't name a single thing you saw. You didn't decide to spend two hours there. Nobody does. Those apps are built by people whose whole job is to decide it for you, and they are very good at it. So EarnLock takes the decision out of the moment and hands it to the one thing that can't be talked around: your body. MOVE FIRST. SCROLL LATER. Pick the apps that keep eating your evenings. Pick what a day of effort looks like — steps, active minutes or calories. Until you get there, those apps don't open. When you get there, they open by themselves, for the rest of the day. No timer to wait out. No "five more minutes." No argument at all, because there's nobody to argue with. Apple Health keeps score, and steps are hard to fake from the sofa. WHY THE LAST ONE STOPPED WORKING Every blocker you've tried left the key in your pocket: a password you chose, a delay you can sit through, a screen you dismiss twice and never see again. It holds for a week — until the one night it doesn't. After that it never holds again. EarnLock puts the key where your 11pm self can't reach it: a few thousand steps away. You can still get in. You just have to briefly become the kind of person who goes outside. That's the whole idea. Not discipline. A price. WHAT ACTUALLY CHANGES For the first week, EarnLock blocks nothing. It watches, so you see the real number before you judge yourself by it. Most people are surprised, and not pleasantly. Then the locking starts, and something quiet happens. You head out at 8pm meaning to check one thing, and come back having forgotten. Days stack into a streak. The grid on your Home Screen fills in, square by square, with proof that isn't a feeling. Half-days count too: reach 50% and an hour opens immediately. Effort always buys something. HONEST BY DESIGN Nothing leaves your iPhone. Not a step, not an app you locked, not a streak. No account, no login, no server, no analytics — there is nowhere for it to go. Health data is read-only and stays where it was. The free tier is a real one: one blocked app, real step tracking, your streak and every widget, forever. No trial that bills you on day three. No countdown invented to hurry you. If you upgrade, it's on a day you chose. WHAT'S INSIDE · Lock any app or category with Apple's own Screen Time controls · Earn with steps, active minutes or active calories · Halfway to your goal opens an hour, right now · Separate goals for workdays, evenings and weekends · Rest days you bank by going further — a streak that survives real life · A contribution grid of every day you earned, on your Home Screen · Apple Watch app, Live Activity and a Dynamic Island countdown · One tap to answer "what am I actually looking for right now?" · Siri, Shortcuts and a Control Center button for today's progress · 39 languages, full VoiceOver, text that scales to the largest sizes IF YOU'VE UNINSTALLED ONE OF THESE BEFORE Then you know how it goes: two good weeks, one bad night, gone. That isn't a character flaw. It's what happens when the only thing standing between you and the app is you. Put something real in the way — something you can always get past, on foot. Move first. Scroll later. —— Free forever: one blocked app, steps, streaks and every widget. Premium adds unlimited apps, every activity unit, Apple Watch, Live Activity, Smart Schedules, insights and rest-day shields — monthly, yearly, or one payment for life. Family Sharing included on every paid plan, for up to 6 people. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the period ends. Manage or cancel anytime in Settings.
