这位朋友您好，我调研了一下后发现有些关键体验需要 iOS 18才能支持，反复权衡之后还是没办法降低到 iOS 17。非常抱歉给您带来了不好的体验。不过支持 iOS 17 的手机都能够直接升级到 iOS 18，如果您愿意的话也可以考虑升级下系统。 再次对给您带来的不便表示歉意，祝您生活愉快。
Nenrin is a diary app that uses 365 Markdown files, one for each day of the year. Entries for the same date are stacked under a '## year' heading, allowing you to see your writing history for that specific day across multiple years.
The app opens to today's page, with past years displayed as chips above the entry. You can tap these chips to switch between years or pull down on the text to go back. Skipped years are highlighted and can be filled in later.
Yes, Nenrin uses plain Markdown files that can be opened and edited in any Markdown editor. Your diary files can be stored locally on your iPhone or in iCloud Drive, making them accessible across devices.
No, Nenrin does not contain advertisements. The app is free to download and use, with optional in-app purchases.
Nenrin offers full-text search that spans all your entries across all years. You can search for a specific word and see its occurrences across your entire journaling history.
The 'Year' view presents a heatmap of all twelve months. Each cell represents a file, and darker cells indicate days where you have written entries for more years, visually representing your consistent journaling habit.
Currently, Nenrin is supported on iPhone. The developer has indicated that Nenrin for Mac can write to the same iCloud Drive folder, allowing for cross-device synchronization.
The latest version of Nenrin is 1.6.0, last updated on October 23, 2026. This indicates a relatively frequent update schedule for the application.
