@shubh5 Really appreciate it, Saurabh. Can’t wait for you to try Cal ID and tell us how we can make it even better.
Monetizing meetings is a great concept. Call ID is in a mission to change the way call scheduling work.
Congrats on the launch. Good luck guys
@nareshmeetei Thanks a lot, Naresh. Grateful for the support and pumped to build this forward.
great product. Great way to drive user registrations - growth hack by offering premium plan for word of mouth referral
@navin_i Thanks a lot, Navin. Glad you liked the product. The growth push is our way of giving back to early supporters.
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?
@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.
Your booking page is pretty cool, but most schedulers are “good enough” on UI. What’s the measurable impact then?
@muhammad_tahir29 That's an excellent question! The measurable impact of Cal ID's UI is directly reflected in performance: our low-friction design leads to significantly Higher Booker Conversion (more completed bookings), and our streamlined workflow ensures Increased User Efficiency by reducing your management time. We believe better UI delivers better results.
Great point @muhammad_tahir29 , most schedulers do look decent these days, so for us, the impact isn’t just visual, it’s in what happens after someone lands on your booking page.
Here’s where Cal ID makes a measurable difference:
Higher completion rates – fewer drop-offs because of the distraction-free flow
Faster setup – most users get fully configured (with branding and integrations) in under 5 minutes
Fewer no-shows – built-in reminders and timezone handling reduce misfires
Shorter sales cycles – teams using routing and paid links see faster booking-to-close conversion
Curious to hear, what would you want to measure more in your scheduling flow? We're building smarter insights next.
