SyncWhen is a free scheduling poll tool built for speed. Create a poll with possible time slots in 30 seconds, share a link, and participants vote yes, maybe, or no on each slot. Results update in real time via WebSocket โ€” no page refresh needed.

Unlike older tools, SyncWhen requires no account from anyone (creator or voter), shows zero ads, and includes yes/maybe/no voting free โ€” features competitors paywall. It's built mobile-first and works in 12 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Turkish, Indonesian, Vietnamese, Arabic.

Recurring polls support weekly or monthly meetings with one shared link. Calendar export to Google, Apple, and Outlook via .ics file. ActionCable-powered live updates mean votes appear instantly as people respond.

Built for teams, study groups, families, and anyone coordinating time across a group without the back-and-forth of email or chat.

Questions & Answers

As answered by people managing Mendix and SyncWhen.

What makes your product unique?

SyncWhen's answer:

SyncWhen is the only free scheduling poll where both creators and voters skip signup, voting is true yes/maybe/no (not just yes/no), and results update live via WebSocket โ€” while staying completely ad-free. It also ships in 12 languages out of the box, including German, Arabic, and Vietnamese, which is rare in this category.

Why should a person choose your product over its competitors?

SyncWhen's answer:

Three reasons: (1) zero friction โ€” no one needs an account, not the organizer, not the participants; (2) real-time results โ€” votes appear instantly without page refresh; (3) it's genuinely free โ€” no ads, no paywalled features, no data sales. Competitors like Doodle lock yes/maybe/no voting, ad removal, and calendar sync behind $6.95+/month paywalls. SyncWhen includes all of it for free.

How would you describe the primary audience of your product?

SyncWhen's answer:

Anyone coordinating time across a group without wanting the overhead of a meeting platform: small teams planning weekly syncs, study groups and classmates, families organizing get-togethers, hobbyists scheduling club meets, and educators running office hours. Mobile-first design means participants can vote from a phone in seconds, which is where most group-chat invites get opened.

What's the story behind your product?

SyncWhen's answer:

SyncWhen started as a reaction to how bloated scheduling polls had become. Doodle used to take 30 seconds โ€” now it's account creation, cookie banners, upsell modals, and ads. The premise: strip it back. One URL, three voting options, real-time results, no friction for anyone. Built as an indie product, 12 locales shipped at launch to reach users who don't get served by US-centric tools.

Which are the primary technologies used for building your product?

SyncWhen's answer:

Rails 8, Vue 3 (Composition API), PostgreSQL, ActionCable for real-time updates, Puma, Propshaft, Solid Queue / Solid Cable, Tailwind CSS v4. Deployed on a self-managed VPS with nginx + Let's Encrypt.
