What Jyn is
Jyn is a free, open-source personal task manager for the terminal. It captures and organizes todos with due dates, tags, five priority levels, reminders, and recurring task series. Tasks can sync to Apple Reminders, Google Tasks, and Microsoft To Do. Through CalDAV, mobile access can include Apple Reminders and Google Calendar, although there is no native app. Jyn runs on Linux, macOS, and Windows, stores data as plain text in your repository using Joy’s data model, and requires no account, server, or configuration. Joyint orchestration can show Joy items assigned to a person alongside personal todos. The software is MIT licensed, with a Free plan at no cost, billed free forever. Installation options include a shell script, winget or PowerShell on Windows, and cargo install. The repository describes Jyn as pre-development, and offline access is unavailable.
