When2Sync is a free When2Meet alternative and Doodle replacement that requires no account from organisers or voters. Poll a time slot on a colour-coded heatmap, or poll a whole date with Plan by Day - up to six months ahead, where people can answer Maybe instead of being forced into yes or no. Share the link and the best option is obvious. No ads, no sign-up, no email - and a built-in DST-aware timezone converter.

When2Meet is the original grid-based availability poll - simple, free, and no-account. Its UI has barely changed in over a decade, and on a phone the dense grid is hard to use. When2Sync keeps the same one-link, no-account workflow but renders the grid with modern touch targets, drag-to-select on both desktop and mobile, and a colour-coded group overlap that updates instantly as people respond.
When2Sync also adds per-participant timezones and a standalone DST-aware timezone converter - both useful when even one person on the call is in a different region.
The bigger gap is that When2Meet only answers "what time?". A lot of plans - a birthday, a group dinner, a weekend away - are settled by picking a date, and a 15-minute grid is the wrong instrument for that. Plan by Day asks the day-level question instead, up to six months out, and hands the answer to the time grid afterwards if you still need one.
Doodle is the most well-known group scheduling brand, but its free plan shows ads on every page including the voting page your participants see, and core features (calendar sync, no-ad polls, multiple active polls) are gated behind a paid tier. Many groups simply want to find a time once a quarter without paying or showing ads to colleagues.
When2Sync is fully free with no ads anywhere, no upsells, no participant cap, and no organiser account. If your use case is "find one good time, send the link, move on" then Doodle's account-and-billing model is overkill - When2Sync covers the same ground in seconds.
The one thing Doodle used to do that When2Sync did not was the date poll - asking which day works rather than which time slot. That is what Plan by Day is: open a window of up to six months, and everyone marks each date Free, Maybe or leaves it blank. The Maybe matters - over a long horizon, forcing people into yes-or-no gets you confident answers that are wrong. So both halves of what people use Doodle for are now covered, and both stay free.
LettuceMeet has a clean modern UI and, like When2Sync, lets people respond from a link without signing up. The differences are in what happens around the grid rather than in getting to it.
When2Sync adds an optional per-participant password, so your entry cannot be edited by someone else who opens the same link - useful when you are filling it in from more than one device. It has a built-in DST-aware timezone converter for checking a candidate window lands in business hours everywhere. And it answers the day-level question as well as the time-level one: Plan by Day polls whole dates up to six months out, with Maybe as a third answer, which a time grid cannot express.
When2Sync sits in the same category as When2Meet, Doodle, LettuceMeet, NeedToMeet, Rallly, and Crab.fit - all tools where participants mark availability on a time grid and the group overlap is shown visually. The differences come down to: account requirements, ad presence, mobile UX, and timezone handling.
For comparing times across cities (independent of any specific event), use the free When2Sync Timezone Converter - it is DST-aware, supports IANA identifiers and common abbreviations (ET, PT, GMT, IST, JST, AEST, BST), and lets you compare up to five locations at once.
Create an event in under thirty seconds, share the link, and let your group fill it in. There is no account to set up, no email to confirm, and no paid tier waiting at the bottom of a feature list.
