There are a few tools for group scheduling. Here's an honest comparison - I built estofit, so I'm biased, but I'll try to be fair about where the others are better.
When2meet
When2meet is the OG. It's been around forever and does one thing: you paint your availability on a time grid. It's simple and it works.
Where it wins:
- Time-slot granularity - if you need to find a specific hour within a day, When2meet's grid is great for that.
- No sign-up - just type a name and start painting.
- Fast - the page is tiny and loads instantly.
Where it doesn't:
- Mobile - the time grid is basically unusable on a phone. You have to pinch-zoom and pray.
- Design - it hasn't been updated in years. This sounds superficial, but sharing a dated-looking link in a work chat doesn't inspire confidence.
- No teams - everyone is just a name. You can't separate "must attend" from "nice to have".
Doodle
Doodle is the enterprise option. Calendar integrations, reminders, booking pages, the works.
Where it wins:
- Calendar sync - it can read your Google/Outlook calendar and auto-suggest times.
- Reminders - it nags people who haven't responded yet (genuinely useful).
- Brand recognition - everyone has heard of Doodle.
Where it doesn't:
- Sign-up wall - you need an account to create a poll. Respondents get pushed to sign up too.
- Aggressive upselling - free tier is limited. Want to remove ads? Premium. Want a deadline? Premium. Want more than basic options? Premium.
- Overkill - if you just want to find a date for a weekend trip, Doodle's 47 features get in the way.
estofit
estofit is date-based rather than time-based. You're picking which days work, not which hours. This makes it ideal for multi-day events, trips, and anything where "which weekend" matters more than "which hour".
- No sign-up - not for the creator, not for respondents. Zero friction.
- Mobile-first - drag-select calendar that actually works on a phone with touch support.
- Teams - split people into groups and see availability by team.
- Yes/Maybe - two-tier availability so people can signal "I can make it work" vs "I'm definitely free".
- Heatmap - visual overview of the best dates at a glance.
Where it doesn't win: if you need time-slot precision within a day, When2meet is better for that. If you need enterprise features like calendar sync and booking pages, Doodle has you covered.
So which one?
Use whatever works for your situation:
- Finding a specific meeting time → When2meet
- Enterprise scheduling with calendar integrations → Doodle
- Finding which dates work for a group event → estofit
Or try all three and see what sticks. They're all free to use (Doodle mostly).
