NoLen
Read full descriptionHide full description
NoLen is a notes app that turns natural-language writing into schedule candidates you can review and organize. Write as you normally do. NoLen finds dates, times, durations, and recurring plans in your text and presents them as candidates. Check the title, date, time, and type, then add the items you choose to NoLen's calendar. Organize work and personal notes with categories, tags, search, internal links, and subnotes. Select text to create a subnote while keeping its connection to the original note. Attach files and protect notes with device authentication where supported. View notes and schedules together in the calendar view. On Mac, see your notes and calendar in one workspace. Your original content remains plain text, while parsed schedule information is stored separately. Data is stored locally first. When iCloud sync is available in the build and enabled by you, NoLen uses Apple CloudKit. Notifications follow your device permissions. NoLen does not automatically confirm or add schedules. Review each candidate and choose what to add.

Verdict
The clearest difference is in-app purchases: NoLen at none against OwlCal's 1. NoLen also leads on update cadence (every 2 days vs every 4 days). OwlCal's advantage is iOS requirement (15.0 vs 18.0). On price, ads and device support there is nothing between them.
