Teamup vs UCals

Teamup Calendar is a cloud-based group calendar for organizing schedules, resources and teams. It offers 12 views, including year and table formats, and nine permission levels. Calendars can be shared through links without requiring recipients to have accounts. Events support custom fields, images and file attachments, and can also be shared as individual event pages. Teamup lists integrations including its API, iCalendar feeds, Slack, Microsoft Teams, Trello and Zapier; it provides iOS and Android apps and one-way calendar sync. The free plan allows five sub-calendars and five users. Paid plans start at $12/mo billed yearly, with a 3-day trial. Teamup says it is ISO/IEC 27001 certified and compliant with EU GDPR, and describes encryption for connections, stored data and backups. Its production services are hosted on AWS, with user content redundantly stored in Oregon and Ireland. Private-server hosting is unavailable.

UCals is an AI calendar assistant that manages schedules through natural-language conversation. One instruction can make multiple calendar changes, and later messages can use earlier conversational context. Its plan covers 11 life categories, including work, meals, exercise, and travel. Two-way synchronization is available with Google Calendar, Apple Calendar, and Microsoft Outlook. Tools include conflict detection, travel-time calculation, multi-currency cost tracking, location intelligence, learned preferences, and linked events. UCals displays before-and-after details for changes, and saying “undo” reverts the last change. Its MCP server connects calendars to Claude Desktop, ChatGPT, Cursor, and other compatible assistants. Platforms listed are Android, iOS, macOS, Windows, and an API. UCals says it uses OAuth 2.0, does not store calendar passwords, encrypts data in transit and at rest, and does not sell, share, or train on calendar data. ICS export and priority support are included. A 14-day trial is offered. The Single plan costs $15 a month, billed monthly.
