Nirvana is a to-do list app inspired by Getting Things Done®, available on web, Windows, macOS, iOS, and Android. Users can schedule tasks to appear when they are ready to act, set due dates for to-dos and projects, and organize work with tags, contacts, and areas. Filters can narrow tasks by tag, area, contact, energy, time needed, and other criteria. Notes support checklists, and search covers words in both to-dos and notes. Email forwarding can turn a message into a to-do, while users can choose days to receive their Focus list by email. Tasks stay up to date across devices, and the app supports reminders, subtasks, and recurring to-dos. Calendar sync is not supported. The free plan includes up to five projects and two areas; Pro costs $3 a month, billed annually at $36/year, and includes unlimited projects and areas, recurring to-dos, and priority support. The MCP server is available on every account, though free users cannot update existing tasks through it.
