I tried When2Meet on my phone again. Then we built something better.

I owe When2Meet a thank-you. It taught a whole generation that a colour grid beats fifty reply-all emails. I have used it for study groups, team syncs, and family reunions. But the last time I opened it on my phone — squinting, tapping, accidentally painting the wrong hour — I thought: why does this still feel like 2007?

That afternoon we were trying to plan a five-person lunch. Desktop would have been fine. Nobody was at a desk. I was on a bus. The cells were tiny. Dragging across the grid felt like a mini game I did not sign up for. Meanwhile a colleague sent a Doodle link that asked her to create an account before she could even mark Tuesday.

Scheduling should not require a spreadsheet, a login screen, and a prayer that mobile drag works.

We built Free2Meet because we wanted the heatmap idea to survive the modern world: phones, time zones, WhatsApp groups, and people who will not create yet another account to say they are free Thursday at 2.

When2Meet: still brilliant, still stuck in time

Credit where it is due: When2Meet is free, fast to set up, and the overlap grid is intuitive once you are sitting at a laptop. For a quick academic group or gaming clan on desktop, it remains a legend.

When2Meet also assumes you always want times, not just dates. Sometimes you only need “which day works?” before you worry about hours. That sounds small until you are coordinating a multi-day offsite and half the group is still in the “which week?” phase.

Doodle: polished, but the free tier fights you

Doodle is the tool corporate teams already know. The UI is familiar. Integrations exist. But if you have sent a Doodle recently as a guest, you know the friction: ads, nudges to sign in, and the sense that you are the product in someone else’s funnel.

Doodle also shows availability as ticks in a list-like grid — fine, but you still end up counting who said yes to what. We wanted the darkest green slot to scream “pick this one” without mental arithmetic.

Free2Meet: what we changed (and what we kept)

We kept the heatmap. We kept the “no account to respond” philosophy. We added mobile-first drag painting, automatic time zones, a dates-only mode, and a live group view that updates as people answer — no refresh spam in the group chat. Cells are sized for thumbs; the group heatmap scrolls naturally on a phone.

Datetime on mobile

Group heatmap on mobile

• No login for respondents — open link, paint slots, close tab.
• Mobile-first grid — built for thumbs, not mouse precision.
• Live heatmap — overlap darkens as answers arrive.
• Dates-only mode when time can wait.
• Free core workflow — create, share, collect, and read the heatmap without artificial caps.

Side-by-side: the stuff that actually matters

Our honest verdict

Doodle — Best when your organisation already lives in that ecosystem and people tolerate sign-in prompts. Less ideal for casual groups who want zero friction.

When2Meet — Still our nostalgia pick on desktop. Free, proven, heatmap-native. We just could not recommend it anymore for phone-heavy groups.

Free2Meet — Obviously we are biased — we built it. But it is the tool we send to friends now: one link, parallel answers, obvious best slot, works on the device people actually use.

Questions we get

We still open When2Meet out of habit sometimes. Free2Meet is what we send when we care about the people on the other end of the link. — The Free2Meet team
