What It Is

TimelineTool is a Google Calendar timeline-view generator designed to fill the gap left by Google Calendar’s lack of a horizontal, Gantt-style scheduling view. It reads calendar data through Google account authorization and displays employee, resource, or project calendars as rows, helping users see scheduling gaps, overlaps, and resource utilization more intuitively.

Core Features and Collaboration

The tool supports adding any Google Calendar for which you have “edit” permission, and you can create multiple Schedules—for example, managing employee shifts, resource bookings, and project plans separately. Events are automatically displayed on the timeline. Users can create, edit, and delete events, drag them to a new time or another calendar row, and adjust event duration; changes are synced back to Google Calendar. View options include Day, Week, Month, Four Week, Three Month, and Six Month, along with search filtering, total scheduled-time statistics for the visible range, working-hour windows, timezone settings, and a default-view setting. For collaboration, public links allow read-only viewing without login, which is useful for temporary schedule sharing. However, the content does not specify more granular role permissions, password protection, or link expiration settings.

Pricing and Trial

Pricing is straightforward: $9.99 monthly or $99.99 annually, with an indicated discount of about 17%. The page states that a free trial is available with no credit card required, but the text mentions both 14-day and 30-day trial periods, so the actual registration page should be treated as the source of truth. Payment methods are not disclosed.

Pros and Cons

Its strengths are clear positioning and ease of use. It is especially suitable for small teams already heavily invested in Google Calendar, offering Gantt-like scheduling visualization at a relatively low cost while retaining two-way calendar sync. The downside is its strong dependence on the Google ecosystem, with no visible integrations for other calendars or enterprise systems. Enterprise-grade capabilities such as security compliance, auditing, SSO, APIs, and self-hosting are also not disclosed.

Who It’s For and Access from China

TimelineTool is suitable for lightweight scenarios such as employee shift scheduling, leave management, meeting room/vehicle/tool bookings, and warehouse or dock scheduling. Access from mainland China cannot be determined from the available content. Since the tool depends on Google Calendar, actual usability may be affected by the availability of Google services. For teams mainly operating in China, alternatives worth comparing include Feishu Calendar, DingTalk Calendar, WeCom Calendar, or tools such as Airtable and Notion that include timeline/calendar views.
