WhenIsGood vs When2Meet — Which Should You Use?

WhenIsGood and When2Meet are so similar that people often use the names interchangeably. Both are free, both require no accounts from respondents, both use a grid-based availability model, and both have been around for well over fifteen years. The differences exist but are subtle. And both share a more significant limitation that matters if your group meets every week.

What they have in common

Both tools solve the same problem the same way: you present a grid of possible times, participants paint the cells when they’re free, and a heatmap shows where the overlap is strongest. No accounts needed from anyone. Both are completely free — no paid tier, no gated features. The core interaction is almost identical: click or drag to fill in availability, hover to see who’s in each slot.

Both have been running largely unchanged for over fifteen years, which is either reassuring (stable, no surprises) or telling (no meaningful development).

Where WhenIsGood differs

The most distinctive thing about WhenIsGood is that the grid is the homepage itself. You don’t pick dates from a calendar first — you select time slots directly on the main page before the event even exists. The grid represents a generic week (Monday through Sunday, morning to evening), and you click or drag across whatever time slots you want to offer.

This makes the creation flow very fast for the organiser. There’s no date-picking step. You select your window, enter your name, and you’re done in about thirty seconds.

The weekly grid structure is also well-suited for finding a recurring slot. Because the grid always represents “a typical week” rather than specific calendar dates, responses naturally map to a standing availability pattern — useful when you’re trying to find a day and time that works most weeks, not just this particular Monday.

Where When2Meet differs

When2Meet uses a calendar date-picker approach. You select specific dates first — click the days you’re considering on a calendar — and then a grid of those specific dates is generated for respondents to fill in. This is better for events tied to a particular date window: “we need to meet before the end of the month” or “I need to find a slot in the next two weeks.”

When2Meet is also significantly better known, particularly in US universities and corporate environments. If you’re scheduling with a group that has likely used it before, the zero-learning-curve factor is real. A scheduling tool only works if people actually fill it in, and familiarity removes a small but meaningful friction point.

How they compare

The limitation they share

Neither WhenIsGood nor When2Meet has any concept of a persistent group. Both are event tools. You create an event, find a time, and the tool’s job is done. The group that attends is just a set of one-time respondents — the tool has no memory of them after the poll closes.

For a recurring group, this means the organiser runs the same cycle manually every single week:

• Create a new event
• Get a new link
• Share it again
• Wait for responses
• Chase the people who haven’t filled it in
• Read the heatmap and make a call
• Communicate the decision separately

After a year, that’s 52 manual scheduling cycles — and it’s always the same person doing it. Neither tool knows your minimum headcount, who your regular members are, or that this group has been meeting for months. Every poll starts completely blank.

Which to use when

WhenIsGood is the better choice when you’re trying to find a recurring weekly slot (the natural weekly grid structure helps), when the organiser wants the fastest possible creation flow, or when the group isn’t tied to specific calendar dates.

When2Meet is the better choice when the event is tied to a specific date window, or when you’re scheduling with a US audience that’s likely already familiar with it.

Neither is the right tool if the group meets every week. The right tool for that scenario is one that models the group itself — persistent members, a standing minimum headcount, and automatic rollover to the next cycle. Toss-up is built for exactly this: set up once, members tap free days in ten seconds each week, and the organiser confirms with one tap. No new grid, ever.
