Aperio
An accessible, keyboard-first calendar, tasks and contacts app for the desktop. Screen-reader-first, local-first, provider-agnostic.
What is Aperio?
Section titled “What is Aperio?”Aperio shows calendars, tasks and contacts from many sources side by side — Google, iCloud / CalDAV, Outlook / Microsoft 365, Exchange, Vikunja, Todoist and purely local lists — in day, week, month, year, agenda and task views. Accessibility is the project’s founding constraint: it is developed and tested screen-reader-first, and every action is reachable from the keyboard.

Built around accessibility
Section titled “Built around accessibility”- Developed and manually tested screen-reader-first (primarily NVDA).

- English and German throughout.
