한국어 매일 아이의 얼굴 한 장. 1년 뒤, 떨림 없는 성장 타임랩스가 됩니다. FaceGrow는 아기·어린이의 정면 얼굴을 매일 한 장씩 모아, 눈 위치를 기준으로 자동 정렬해 부드러운 성장 영상과 졸업앨범 페이지로 만들어 주는 단 하나의 목적에 집중한 앱입니다. ■ 아기 얼굴에 강한 자동 정렬 눈 위치를 기준으로 회전·크기·위치를 맞춰, 매일 찍은 얼굴이 같은 자리에 오도록 정렬합니다. 그래서 타임랩스가 떨리지 않습니다. 아기가 정면을 안 봐도 괜찮아요 — 검출이 어려우면 눈 두 곳을 직접 찍어 정렬할 수 있습니다. ■ 안 기다려주는 아이를 위한 빠른 촬영 직전 사진을 반투명으로 겹쳐 같은 구도를 잡아주는 고스트 가이드, 한 번에 여러 장을 찍고 가장 잘 나온 한 장을 고르는 연속 촬영을 지원합니다. ■ 타임랩스 영상 + 졸업앨범 PDF 기간과 속도를 골라 mp4 영상을 만들고, 1년치 얼굴을 졸업앨범처럼 배치한 PDF로 내보내 인쇄하거나 가족과 나눌 수 있습니다. ■ 온전히 이 아이폰 안에서 모든 얼굴 검출·정렬·합성은 기기 안에서만 이루어집니다. 사진은 외부 서버로 전송되지 않고, 회원가입도 없습니다. iCloud를 쓰면 내 기기끼리만 안전하게 동기화됩니다. 여러 아이를 각각 독립된 타임랩스로 기록할 수 있습니다. 오늘의 첫 얼굴을 남겨보세요. 1년 뒤가 기대돼요. English One photo of your child's face a day. A year later, a smooth, jitter‑free growth timelapse. FaceGrow does one thing well: it collects a daily frontal face photo of your baby or child, auto‑aligns by eye position, and turns it into a smooth growth video and a yearbook page. ■ Alignment built for baby faces — rotation, scale, and position are matched by the eyes so every day lands in the same spot. If a face is hard to detect, just tap the two eyes to align manually. ■ Fast capture for kids who won't wait — a ghost overlay of the previous photo helps you match the framing, and burst capture lets you pick the best shot. ■ Timelapse video + yearbook PDF — export an mp4 or a printable yearbook‑style PDF to share with family. ■ Entirely on your iPhone — all processing is on‑device. Photos never leave your phone, no sign‑up required. With iCloud, data syncs only across your own devices. Track multiple children as separate timelapses. Capture today's first face — a year from now will be worth it.
