The short answer
Timeful is the better free scheduler for most groups in 2026. It keeps When2meet's availability heatmap but adds a modern mobile-friendly interface, calendar overlays for Google, Outlook, and Apple Calendar while you respond, and email notifications, and it is free and open source. Choose When2meet only if everyone is on a desktop and you value raw speed and familiarity over everything else.
The two tools are more alike than any other pairing in this category: both are free, both use the paint-your-availability grid, and neither forces respondents to create an account. Which is why the comparison comes down to everything around the grid: how it behaves on a phone, whether it knows your calendar, and how it handles time zones.
Below we compare them point by point, answer the safety questions people ask about Timeful, and end with a third option for people who want the lightest possible poll.
What When2meet still does well
When2meet has been running since 2009, free the whole time, and it survives because it nails one thing: speed.
- Fastest creation flow in the category. Name the event, drag over dates and times, done. There is no onboarding, no account, and nothing to configure.
- Everyone has seen it. In universities especially, a When2meet link needs zero explanation. Familiarity is a real feature when you need 15 people to respond.
- The heatmap works. The green overlap grid remains the clearest way ever devised to show a group's mutual availability.
- Completely free, supported by ads.
If your whole group is at laptops and the poll is simple, When2meet still gets the job done, which is exactly why it has outlived hundreds of prettier tools. Our guide to using When2meet covers the flow if you have somehow never seen it.
Where When2meet shows its age
The complaints are the same ones people have had for years, unchanged as of July 2026:
- Phones. The grid is not responsive: cells render tiny, taps misfire while scrolling, and there is no mobile app. Since most respondents now open links on a phone, this is the dealbreaker. We wrote a whole piece on using When2meet on mobile and the honest summary is "you mostly cannot."
- No calendar sync. You answer from memory. One participant who forgets a standing conflict can sink the winning slot. There is no Google Calendar connection of any kind, which we cover in When2meet and Google Calendar.
- Time zones are a raw dropdown. When2meet pre-selects the zone your browser reports, but exposes the full time-zone list as a control with no safeguard, so a wrong device setting or a stray change lands your availability hours off, with no calendar overlay to catch it.
- No notifications, no history. The organizer refreshes the link to check progress, and the per-event name and password sign-in means there is no account or list of your past polls.
None of this is new. When2meet has shown no visible development in over a decade, so the question is simply whether the alternatives fix these gaps without losing the speed. Timeful mostly does.

| Price | Free (ads; open source) | Free (ads) |
| Account needed to respond | No | No (per-event name/password) |
| Availability heatmap grid | Yes | Yes |
| Works on mobile | Yes, responsive | Barely; tiny non-responsive grid |

| Email notifications and reminders | Yes | No |
| Time zone handling | Handled by the app | Manual dropdown |
| Open source | Yes (AGPL v3, self-hosting docs) | No |
| Speed to create a poll | Fast | Fastest |

What Timeful gets right
Timeful (formerly Schej) started as a student project posted to Reddit as "I made a better when2meet" and grew into one of the most liked free schedulers, especially among students. The pitch is exactly what the Reddit title promised: the same grid, modernized.
- Calendar overlay for Google, Outlook, and Apple Calendar. While you mark availability, your own events appear beside the grid, so you paint around your real schedule instead of guessing. This is the single biggest practical upgrade over When2meet, and it covers all three major calendar ecosystems.
- Modern, mobile-friendly interface. The grid is responsive and pleasant on a phone, which fixes When2meet's worst problem outright. It also schedules across time zones and sends email notifications and reminders.
- Free and open source. The code is public under AGPL v3 with roughly 1,700 GitHub stars (checked August 2026), there is no paid tier, the project is actively maintained, and there are real self-hosting docs for Docker Compose and NixOS. The hosted site currently includes Google AdSense and accepts donations.
- Power features When2meet never dreamed of. "Available" versus "If needed" times, viewing overlap for a subset of respondents, duplicating polls, availability groups with real-time calendar availability, CSV export, and a plugin API.
The limitations are narrow. It is a small project rather than a company with support staff, though the open source model softens that concern. And the feature depth, while genuinely useful for regular organizers, is more than a casual five-minute poll strictly needs.
Verdict: which should you use?
Use Timeful for essentially every real-world group. Calendar overlays for Google, Outlook, and Apple, email notifications, time zone handling, and a grid that works on phones make it better than When2meet across the board. Students, clubs, friend groups, and anyone who wants depth or open source are the perfect fit.
Use When2meet only in one scenario: everyone is on a desktop, the poll is a one-off, and the group already knows the tool so well that familiarity beats every feature. That scenario exists, mostly in universities, but it is shrinking every year, and it is nostalgia as much as it is a decision.
If you are choosing for a group, the tiebreaker question is simply: will anyone respond from a phone? If yes, When2meet is out, and the real comparison is between Timeful and the other modern grids. Our roundup of the best When2meet alternatives ranks seven of them if you want the wider field.
A third option: the lightest possible poll
Timeful's depth is a genuine strength, and it is also more product than every poll needs. If you are scheduling one pizza night, features like availability groups, subset filtering, and a plugin API are things to scroll past rather than things to use.
Timespree is built for exactly that case: the same free availability heatmap, deliberately kept light. Respondents need no account, the grid is mobile-first, and while responding anyone can overlay their busy times from Google Calendar, Outlook, or Apple Calendar (CalDAV), free. It never auto-fills without you; it just shows your real schedule under the grid. It also supports if-needed availability, lets signed-in organizers export responses to CSV, names the event's base zone with converted details in a chosen display zone, and emails the organizer as responses arrive.
To be clear about limits: Timespree has no native mobile apps (the web grid is mobile-first and works well on phones), it is not open source, and it does not have Timeful's availability groups, subset filtering, plugin API, or self-hosting. Timeful uses ads and also accepts donations. Timespree is the lighter tool, not the deeper one. Creating a poll takes about a minute.
