SingularityApp vs Vikunja

SingularityApp is an AI-powered planner that brings tasks, notes, reminders, and a Pomodoro timer together. It supports calendar planning, priorities, recurring tasks, and nested projects and tasks, along with a habit tracker, stopwatch, and time-tracking statistics by task, project, and tag. It runs on web, Windows, macOS, Linux, iOS, and Android. Google Calendar sync can be one-way or two-way; with two-way sync, changes to synced tasks are reflected in the calendar. Other listed integrations include web calendars, Telegram and email task capture, an API, and MCP. Projects can be shared with up to five members on Pro or ten on Elite. The Basic plan is free and allows up to 10 projects, five sections per project, three habits, one reminder per task, and one device. Pro costs $3.33 a month billed annually; Elite costs $4.17 a month billed annually. A 14-day Elite trial does not require a credit card. Minimum requirements include Windows 10 64-bit, macOS Sierra, Android 10, and iOS 13 or later.

Vikunja is an open-source task and project management app that can be self-hosted or used through cloud plans. Tasks can be organized as lists, Kanban boards, Gantt charts, or tables, with due dates, reminders, repeating schedules, subtasks, labels, priorities, assignments, attachments, and relations. Projects can be shared with another user or team, or through a link that does not require an account. Vikunja includes CalDAV integration and migration support for Todoist, Trello, and Microsoft To-Do. The self-hosted core is free under the AGPLv3 license, but server maintenance, updates, and backups are self-managed. Paid cloud plans start with Personal at €4 a month, including 10GB of attachment storage. Family costs €10 a month for up to five users, while Organization costs €5 a month per user. Vikunja Cloud is hosted at Hetzner locations in Germany and Finland. Desktop apps are available for Linux and Windows; the maker notes that mobile apps support only very basic features.
