Reviewers say Cal ID makes scheduling easier and cuts the usual back-and-forth, with praise for quick setup, clean booking links, custom schedules, multi-calendar sync, reminders over email and WhatsApp, and payment support through Razorpay. Users also value how many features are available without early limits, especially for teams. The main criticism is polish: some find parts of the UI cluttered, advanced setup can feel heavy for non-technical users, and one reviewer reported slow booking or cancellation and problems with Jitsi. A founder of
HTTPDump adds that team routing and support have worked well at scale.

Love the open-source approach, Do you plan to integrate with tools like Notion or ClickUp soon? It would be awesome to connect scheduling directly with task management.

@haiqa_irfan We’re exploring possibilities like this - feel free to share any specific use cases you’d love to see supported!
Love the positioning. How does Cal ID handle timezone detection and buffer logic compared to the bigger players?
Cal ID
@himani_sah1 Cal ID automatically detects each attendee's timezone and adjusts available slots accordingly, just like other scheduling tools. However, we also have a "Lock Timezone" option for fixed-time events and "Buffer Control" to manage prep or cooldown time.
We detect timezones automatically and handle buffer times intuitively - just set it once and it works across all your events.
