SyncThemCalendars is a calendar-sync SaaS provided by Monkey Cube Studio PTE LTD, registered in Singapore. It addresses the problem of busy/free time and events not staying in sync across multiple calendars, including Google Calendar, Microsoft Outlook/Office 365, and Apple iCloud. Its main selling points are a 2-minute setup, automatic background operation, and privacy protection.
The product lets users create syncs between two calendars by choosing a source calendar and a destination calendar, then copying future events. Sync can be one-way, two-way, or multi-directional, making it useful for unifying availability across personal, work, and client calendars. A key highlight is event-field control: users can hide details such as titles, descriptions, and locations, or sync only busy/free status, helping prevent private events from being exposed to an office or client. For third-party integrations, the site explicitly supports Google Calendar, Microsoft Outlook/Office 365, and Apple Calendar/iCloud, but we did not find information about CRM tools, project management integrations, APIs, or webhooks.
SyncThemCalendars is a paid subscription service with a 14-day free trial and no credit card required. Annual pricing is Basic at $3.99/month, Premium at $7.99/month, and Professional at $17.99/month, supporting up to 5, 16, and 36 sync relationships respectively. Monthly billing costs $4.99, $9.99, and $19.99/month. All tiers include unlimited events and unlimited Google/Outlook/Apple calendars, but each plan is limited to 1 user.
The strengths are a clear positioning and low setup barrier, making it well suited to βset it and forget itβ calendar-sync scenarios. The pricing structure is also easy to understand, and the privacy controls for event fields are practical for separating personal and work calendars. The limitations are mainly around enterprise capabilities: we did not see team member management, role-based permissions, audit logs, SLA details, compliance certifications, or self-hosting options. Although the plans are marketed toward small businesses, the information on the site makes it feel more like a single-user tool.
It is suitable for consultants, freelancers, founders, small business owners, and anyone who uses multiple client or work calendars at the same time. If you need large-team scheduling, enterprise-grade permissions, or integration with China-based office ecosystems, you may need to evaluate alternatives such as Feishu, DingTalk, or WeCom Calendar. Access from mainland China and supported payment methods are not disclosed in the source text, so they should be considered unknown. Before using it, we recommend testing the official website, the Google/Microsoft/iCloud authorization flow, and bank card payment availability.
