Schedule meetings across
time zones — fairly.
The timezone meeting scheduler that stops making the same people take the midnight calls.

Features
Schedule smarter across every time zone.
Sacrifice Score
Track who's bearing the burden of bad meeting times. The algorithm rotates sacrifice so it's not always the same person waking up early.

Golden Windows
Find times when everyone's actually sharp — not just awake. Based on circadian rhythms and cognitive performance research.

Smart detection when a Loom or doc would work better than a meeting. Saves 5+ hours per week on average.
Fair Rotation
Recurring meetings automatically rotate times so no single timezone always bears the cost. Minimizes maximum sacrifice across all participants.

Find the best meeting time for your global team
Add your team members across time zones and discover “Golden Windows” — the times when everyone is cognitively sharp, not just awake. Our algorithm finds the fairest meeting times that minimize sacrifice for all participants.

2Night/early morning meetings earn bonus points
3Algorithm prioritizes members with lower scores
4Scores decay over time to ensure ongoing fairness
See when your team is actually sharp — not just awake
Golden Windows uses circadian rhythm research to find times when your team members are at peak cognitive performance. Schedule important decisions during peak hours and avoid the post-lunch dip — so every meeting actually counts.
10 AM - 12 PM
98% cognitive performance
2 PM - 4 PM
88% cognitive performance
1 PM - 2 PM
Post-lunch dip (60%)
Cognitive Sharpness by Hour
Peak Performance
Best for: Strategic decisions, creative work, complex problem solving
Good Performance
Best for: Regular meetings, updates, collaborative work
Fair Performance
Best for: Status updates, light discussions, email
Low Performance
Avoid meetings during these hours
Sleep hours, evening wind-down. Schedule async instead.
The Science Behind Golden Windows
Our algorithm is based on decades of chronobiology research. Everyone has a unique circadian rhythm, but most people experience similar patterns of cognitive performance throughout the day.
Know when a meeting should have been an email
The Async Nudge detects when timezone spread or low urgency means a meeting isn't worth the sacrifice. Get smart suggestions to use a Loom, Notion doc, or Slack thread instead — and track the hours your team reclaims every week.
