Tweek · Riga, Latvia
What it is
Tweek is a weekly planner and to-do list with week, month, and day views. Tasks can include color tags, notes, files, images, subtasks, and recurring schedules. Reminders can be delivered by push notification, email, or both. Calendars support real-time sharing and can be published for people to view without signing up. The app is available on the web, iOS, Android, and macOS. Premium syncs with Google Calendar, Outlook Calendar, Apple Calendar, and Apple Reminders; Siri can add tasks through Apple Reminders. Sync behavior varies: Google events sync both ways, but Tweek tasks are not sent to Google Calendar, while Outlook events import one way. Tweek also provides a REST API and MCP server for task and calendar access, including by AI assistants. The free plan allows one active calendar and two custom colors. Individual Premium costs $5.99 per month for one person, and Family Premium costs $9.99 per month for up to four people. A 14-day trial is listed.
