Works for everyone

Any group. Any occasion.

Friend groups
Birthday dinners, weekend trips, watching parties. Stop the endless text chain.

Kick-offs, all-hands, recurring standups. Works for 5 people or 500.
Family events
Holiday gatherings, reunions, game nights. Share the link at Sunday dinner.
Recurring meetings
Weekly standups, monthly 1:1s. The recurring engine re-polls your group automatically each cycle.
Remote teams
Across time zones and calendars. The heatmap makes the overlap obvious without the argument.
Clubs & communities
Sports teams, book clubs, volunteer groups. Plan events people actually show up to.

Features

Everything you need.
Nothing you don't.

Share a link. That's it.
Guests need zero setup. Click the link, tap the grid, done. Any browser, any device, in seconds.
Live availability heatmap
Responses arrive in real time. The overlap deepens as people submit — the best time surfaces automatically.
SMS & email confirmation
When you confirm the time, everyone who responded gets notified instantly — by text or email, their choice.
Auto-reminders & deadlines
Set a cutoff so nobody holds the group hostage. Automatic nudges keep response rates high without you chasing people.
Recurring events
Set a weekly or monthly cadence and Synclio re-polls your group each cycle automatically. No manual re-creation.
Private by default
Links are unguessable. Name, email, and phone are always optional. Contact info is auto-deleted after the event. Nothing is ever sold.

No — guests just click the link and tap their availability. No signup, no app install, no friction. Only the organizer needs an account.
Synclio has a live heatmap that updates as responses come in, SMS and email notifications when the time is confirmed, automatic reminders, and a recurring event engine — none of which Doodle or When2Meet offer. It's also significantly faster to set up, with no ads on respondent pages.
The free plan includes up to 5 active polls, email notifications, the live heatmap, and shareable links — no account required for guests. SMS notifications, recurring events, and reminders require a paid plan.
Blocks are a one-time purchase — $5 for 100 SMS, $20 for 500, or $45 for 1,200. They never expire and draw down as SMS messages are sent. Available on Pro and Business plans from your dashboard.
Yes. Cancel any time with one click — no calls, no forms. Your polls stay accessible until the end of the billing period.
Nothing is collected unless a respondent opts in. Name is always optional. If someone provides an email or phone number to receive a confirmation, that data is automatically and permanently deleted after the event passes. Synclio does not sell, analyze, or share respondent data under any circumstances.
