When to use WhenWorks instead
Cal.com owns 1:1 booking. WhenWorks owns group availability.
Built for Groups, Not 1:1
Cal.com is excellent for "book time with me" scheduling. WhenWorks solves a different problem: finding the one time that works for everyone in a group. These are fundamentally different tools.
Zero Setup
No calendar connection required, no OAuth flow, no availability configuration. Create a poll in 30 seconds, share the link, get responses. That's it.
No Account for Voters
Anyone you invite can vote on availability without creating an account. Critical for scheduling with students, clients, or external collaborators who won't install another app.
Mobile-First Voting
Your group votes from their phones. WhenWorks is optimized for touch — drag to select time ranges, tap to confirm availability. Cal.com's booking flow is better on desktop.
When You Don't Know Your Schedule Yet
Cal.com requires you to set your availability in advance. WhenWorks works when the meeting organizer doesn't know their availability either — everyone votes, best time wins.
No Configuration Required
Cal.com requires connecting your calendar, setting buffer times, configuring event types. WhenWorks requires nothing. Just a poll title and some time slots.
Frequently Asked Questions
What is the main difference between Cal.com and WhenWorks?
Cal.com is designed for one-on-one appointment booking — you share your calendar availability and others book slots. WhenWorks is designed for group scheduling — everyone votes on their availability and you find the time that works for the most people. Different use cases.
Can WhenWorks replace Cal.com for booking 1:1 meetings?
Not directly — WhenWorks doesn't integrate with your calendar to show real-time availability or auto-block time. If you need someone to book a specific slot from your live calendar, Cal.com is the right tool. If you need to find mutual availability across a group, WhenWorks is better.
Is WhenWorks free like Cal.com?
WhenWorks has a free tier (3 polls/month) and a Pro plan at $6/month for unlimited polls. Cal.com's cloud version is free for basic 1:1 booking. Both have genuinely useful free tiers.
Does WhenWorks require self-hosting like Cal.com?
No. WhenWorks is cloud-only — you create an account, create polls, and share links. No servers, no Docker, no deployment required.
