I really like being able to look back at photos from the same date across different years, almost like flipping through a personal photo album. Other apps only allow 1-second videos, which always felt too short, but the 3-second clips here are just the right length to capture a moment from the day. It would be even better if there were an option to select a custom date range and watch all the videos from that period compiled together. I'm really enjoying the app and will detinitely keep using it. Thank you! ### 1/5 — Super cute when it works *2026-01-09, version 1.30* I love the concept of the app. I just wish it worked all the time. I can’t upload photos. It stays stuck on the upload screen. ### 4/5 — Good app *2026-01-06, version 1.26* Good app with creative style of scrapbook. But there's some bug that cannot upload photos ### 5/5 — 하루 3초 기록, 진짜 꾸준히 하게 돼요 *2026-01-01* 매일 3초만 기록하면 돼서 부담이 없어요. 글로 쓰는 일기는 자꾸 미루게 되는데, 영상이나 사진으로 짧게 남기니 오히려 더 꾸준히 하게 됩니다. 인터페이스도 단순해서 바로 기록할 수 있고, 기록이 쌓이다 보니 나중에 다시 보는 재미가 커요. 작심삼일 일기 습관 잡기용으로 추천합니다. ### 5/5 — 와 너무 좋은 어플 *2025-12-30, version 1.16* 하루하루 일기쓰기가 어려웠는데 그 하루를 기억하는 어플이네요 사진을 더 많이 찍어 내 하루를 기억하고 싶은 앱이에요 감사합니다 ### 5/5 — 작심삼일 이겨내주는 만능다이어리 *2025-12-29* 요즘 트렌트에 맞게 짧은 영상으로 내일상을 일기처럼 남길 수 있다니 이보다 더 완벽할 수 있을까요?? 과거의 오늘도 볼수있다니 너무 좋잖아요!! 그리구 사진이나 영상 첨부시 날짜별로 사진이랑 영상을 보여주니까 좋네요!! 감사합니다 ### 5/5 — 일기쓰기가 즐거워지네요 *2025-12-26* 평소에 사진찍는걸 좋아하는데 긴 글 필요없이 사진만 넣어도 그날의 일기가 완성되요. 사실 밀린 일기를 한번에 후루룩 쓰는 타입인데 사진들을 넣으면서 그날그날의 추억을 되짚어 볼 수 있어서 좋네요. 한달치를 한번에 보면 폴라로이드 사진들을 달력에 붙여둔 것 같아서 귀여워요 :) 만족합니다! ### 5/5 — 좋은 어플이네요 *2025-12-26, version 1.15* 육아휴직을 쓴 아빠입니다. 아이와 함께 쓰려고 다운받앗습니다. ^^ 앞으로도 잘 쓰겠습니다 ### 5/5 — 너무 이쁘네요~ *2025-12-26, version 1.15* 일기 쓰는 걸 좋아하는데 동영상 일기 좋은 아이디어네요! 맘에 들어요~~ 감사합니다~ ## Frequently asked questions about 3 Second ### What is 3 Second - Diary Short-form?
