OnlyWeekNo. vs Wekly

You can choose the first day of the week, like starting with Sunday or Monday? And you can also choose a rule for the first week of the year. Like ISO 8601, you can choose the first Thursday week as the 1st week, or January 1st as the 1st week, or else.

Wekly is a focused week utility for quickly understanding ISO week numbers, date ranges, and the weekly references that show up in real work. Open the app to see the current week at a glance: the ISO week number, the week year, the start and end dates, and the progress of the week. Move forward or backward week by week, jump to a specific date, or look up a week number and year to get its exact date range without opening a full calendar. Wekly is useful when project plans, class schedules, invoices, release timelines, sprint notes, deadlines, or team conversations refer to Week 12, Week 34, or any other weekly reference. It gives you the answer directly, with a clean interface designed around clarity rather than calendar clutter. The app is intentionally narrow and precise. It is not a task manager, a planner, or a general calendar replacement. It is a calm reference tool for people who think in weeks and need week numbers, week dates, and date-to-week conversion to be fast, readable, and reliable. Built with a native Apple feel, Wekly keeps the details close: localized date formatting, ISO 8601 week logic, week navigation, date lookup, week lookup, copy actions, and widgets for checking the current week from the places you already use every day.
