쪽잠 Pro는 짧은 낮잠과 휴식을 위한 조용한 쪽잠 타이머입니다. 유튜브 영상은 정해진 길이에 맞춰 들어야 하지만 쪽잠 Pro에서는 원하는 시간을 직접 설정할 수 있습니다. 5분, 15분, 30분처럼 자주 쓰는 시간은 바로 선택하고 필요한 경우 시간·분·초를 직접 조절해 나에게 맞는 쪽잠 시간을 만들 수 있어요. 이어폰을 연결하면 알람음이 이어폰으로 재생되어 독서실, 도서관, 사무실처럼 조용한 공간에서도 사용할 수 있습니다. 시스템 볼륨 슬라이더를 앱 안에서 바로 조절할 수 있어 알람이 들릴 정도로 미리 맞춰둘 수 있습니다. 잠금화면과 Dynamic Island에서는 남은 시간을 확인할 수 있고, 5분 간격 반복 기능을 켜두면 앱에서 알람을 끄기 전까지 다시 울리도록 설정할 수 있습니다. 주요 기능 - 원하는 쪽잠 시간 직접 설정 - 자주 쓰는 시간 빠른 선택 - 일어날 시간 기준 알람 설정 - 이어폰으로 조용한 알람 재생 - 앱 안에서 시스템 볼륨 조절 - 잠금화면 및 Dynamic Island 남은 시간 표시 - 5분 간격 반복 알람 - 처음 사용하는 사람을 위한 튜토리얼 주의 앱을 완전히 종료하지 않고 백그라운드에 둔 상태에서 사용해주세요. 기기 또는 이어폰의 시스템 볼륨이 0이면 알람음이 들리지 않을 수 있습니다.

When one late reply takes over your day. Stay in love. Stay yourself. Become Secure connects a 20-question attachment style quiz with small daily relationship practices. Understand your reactions and find one next step, designed for about two minutes a day. KNOW YOUR PATTERN Want closeness, then find yourself pulling away? Notice anxious and avoidant reactions through a self-check. Pause and resume your questions, then receive a first exercise based on your answers. ONE PRACTICE FOR TODAY Separate facts from guesses when a text goes unanswered. Say you need space instead of disappearing. Put a feeling into words. Practice communication, boundaries and self-care in everyday moments. Add a private note if you want to. MAKE ROOM BEFORE YOU REACT Try a 60-second pause when your mind feels busy. Hold the button to continue and release to pause. Moment reflection and a three-minute mindfulness practice are also available. 31 PRACTICES, AT YOUR PACE A missed day does not erase completed steps. Preview your next exercise and return when you are ready. YOUR NOTES STAY YOURS Start without an account. Answers and notes stay on your device, without cloud sync. Public cards include the practice, counts and drawing, never quiz answers, scores or private notes. The app interface supports English and Korean. A non-medical tool for self-understanding and relationship skills. The self-check is not a clinical assessment. The app does not diagnose or treat conditions, or promise a change in attachment style within a set time. YOUR PRACTICE, DRAWN IN A LINE Each completed day carries a red line a little farther. See an immediate visual reward after your exercise and revisit your progress in a 31-step record. The drawing represents completed practices, not a clinical measure of attachment or emotional health. Share a practice card as an image. In supported environments, open an Instagram Story, Threads or X composer. Image and text transfer and app opening depend on your device and installed apps. You decide whether to publish.
