Why scheduling this is hard
A PI, postdocs, and grad students all juggle teaching, lab hours, and fieldwork with no shared calendar.
Collaborators sit in different time zones, so a slot that looks fine for one is midnight for another.
Weekly lab meetings drift because someone new is always double-booked with a class or seminar.
How the poll works
Create your poll
Pick the dates and time range you want to offer. Your shareable link is ready in under a minute.
Share one link
Send it wherever your group already talks. Nobody needs an account to respond, on any device.
Read the heatmap
Every response shades the grid. The darkest slot is your time. Done.
Why Timespree fits
Overlap across bench time and teaching
Each member shades free hours around lab work, classes, and office hours, and the common slot surfaces at once.
Automatic time-zone conversion
Everyone shades in their own local time and Timespree converts it, so a collaborator abroad sees the slot correctly.
No participant limits
A three-person project or a full lab of fifteen fits in one poll, always free.
Calendar overlay while responding
Members can overlay Google or Outlook busy times so a seminar or class does not get double-booked.
A real example
A neuroscience lab of eleven, including two collaborators in Berlin, needs a weekly meeting. The PI's grad student sends a poll spanning Mon-Fri mornings; everyone shades their free time in their own zone. Tuesday 10 AM Boston time, which is 4 PM in Berlin, is darkest and works for both sides, so it becomes the standing meeting.
Frequently asked questions
- How does Timespree handle collaborators in other time zones?
- Each person shades their free hours in their own local time, and Timespree converts everything automatically. The heatmap shows a single overlapping slot, and each viewer sees it in their own zone, so no one does mental math.
- Can we include undergrads and staff without accounts?
- Yes. Everyone from the PI to a first-year undergrad opens the same link and shades their free hours with no sign-up, so the whole lab responds without anyone being blocked by a login.
- Is there a cap on lab size?
- No. Timespree has no participant limit, so a small project team or a large lab with rotating members all fit in one poll, and it stays free regardless of how many people respond.
