What's New in When'd I

5.1.0

November 2, 2026

"Report" is now split into "Monthly · Yearly · All". Monthly and yearly Recap cards let you look back on a month or a year and share them as images. Tap a date in the monthly calendar to jump to that day in "Catalog". Use "Records · Overdue" at the top left of Home to see only your overdue items. You can also swipe left or right to switch, and "Complete" takes an item off the list. Tap the input field on Home to choose "Date · Time · Category" as you record, and search now finds record notes too. "Catalog › Calendar" shows each day with that day's photo, and you can record several items at once on a chosen day. In an item's details, each record shows how much time has passed, like "1 year 2 months 3 days ago".

Worthless

It’s impossible to change the date on a task. It records the task is happening right when you enter it. Trying to change the date on the task, simply results in multiple entries. It’s unbelievable how easy this should be to fix but here we are. Good idea, terrible execution.

Response from developer

Thank you for your feedback. However, I’d like to clarify that the feature you mentioned already exists in the app. For convenience, adding a record directly from the home screen automatically uses the current date. This is intentional, so users can quickly record something they just did. If you want to record something that happened on a different date, simply tap the item to open its details and select “Add Another Date.” You can then choose the date you want. Please take another look at this feature, as the app does support recording past dates. If you’re still having trouble or aren’t sure how to use it, please feel free to contact me by email. I’ll be happy to walk you through it. I hope this clears up the misunderstanding. Thank you!

투머치 기록러에게도 만족하는 기록 어플🙌🏻

저는 이것저것 많이 기록해놓고, 저장해놓고, 달력을 알록달록 꾸미는 걸 좋아해요. 하지만, 막 이것저것 다 기록해놓다보면 가끔 제가 뭘 해야했더라, 언제했더라. 까먹고 찾거나 체크하는것도 나름 일입니다ㅠㅠ 이 어플은 간편하게 틱 눌러서 내가 한 일들 바로 시간까지 기록가능하고요. ‘언제했지?’ 라는 이름에 걸맞는 심플하고 간편한 어플입니다·͜· 내가 기록한 마지막 날짜부터 얼마나 지났는지 알려주며, 친근하게 말걸어주는 느낌이라 더 마음에 들었어요. 처음 사용했을때보다 편의성이 높아졌어요,개발자님이 신경을 많이 쓰고 계신 게 느껴집니다(◞ꈍ∇ꈍ) 피드백도 하나하나 받으시며 심플한 UI도 놓치지 않으시는 것도 최고! 간편하게 내 루틴 기록하고 싶은 분들부터, 저같이 투머치 기록러들도 힘빼고 가볍게 기록 하나를 더하고 싶다는 분들까지 모두 좋을 것 같아요✨요청사항이 있다면 알림의 주기를 설정할 수 있거나 받고 싶은 기록(또는 카테고리)만 알림설정이 가능했으면 좋겠어요.

편안하게 내 기록과 습관을 추적!

내가 ‘한 일’을 온전히 기록해 주는 방식이라 마음이 정말 편안해요!
가장 좋은 점들을 꼽자면,
엄청나게 직관적인 사용성! 버튼 한 번만 누르면 될 정도로 과정이 간단하고 편해서 꾸준히 쓸 수 있었어요
그리고 똑똑한 트래커 역할! 한동안 신경 쓰지 않고 편하게 사용하다가 돌아보면, 그동안의 기록이 깔끔한 리포트 형태로 쌓여 있더라고요. 내 활동 흐름을 한눈에 돌아볼 수 있어서 정말 유용했습니다ㅎㅎ

할 일 압박 없이 편안하게 내 기록과 습관을 추적하고 싶은 분들께 강력히 추천합니다! 앞으로도 계속 잘 사용할 것 같아요👏

편리해서 JOAH !

육아하면서 깜빡깜빡하기 쉬운 항목들을 정리할 수 있어서 좋아요! 무엇보다 직관적이구 깔끔한 레이아웃에 반합니댜••❤️
