Supported

Dark Interface

Every surface renders on an obsidian background. There is no light mode.

Reduced Motion

Turn on System Settings ▸ Accessibility ▸ Display ▸ Reduce Motion. Aion resolves its launch sequence to a still frame, snaps the date and year dials, and stops its ambient motion. Colour and opacity changes remain.

Differentiate Without Color

Colour never carries meaning alone: every entry’s time is also stated in digits. The Calendar shows how much you wrote through size and weight. The Patterns rosette places each hour by clock position and petal length, with the exact count on hover.

Keyboard

⌘1 ⌘2 ⌘3 open Calendar, Chronicle, and Patterns. ⌥⌘← ⌥⌘→ move between them

⌘F search. ⌘G and ⇧⌘G step through results

⌘N new day. ⇧⌘⌫ delete the day

⌘; show misspelt words. ⌥⌘; correct them

⇧⌘E export the day, year, or everything as text or Markdown

⌘B ⌘I ⌘U ⇧⌘K ⇧⌘X bold, italic, underline, small caps, strikethrough

Arrow keys move within the Calendar and rosette. Esc steps back out of any state

The command language is typed: cd, !remindme, !birthday, /similar, /lexicon

Known limits

VoiceOver

Writing, reminders, and footer confirmations are built to work with VoiceOver. The Calendar and the rosette announce a summary rather than every cell; to move through days, use the date dial and search.

Sufficient Contrast

The time-of-day text colour can fall below WCAG AA at some hours, worst in the late afternoon tones on black. A higher-contrast reading mode is planned.

Larger Text

Aion uses a fixed, page-proportioned layout. It does not adopt Dynamic Type. macOS System Zoom (⌃-scroll) and the Larger Text display setting both magnify the window.

Captions and Audio Descriptions

Aion has no spoken or video content. No meaning is carried by sound. The launch tone is silent under Reduce Motion.
