Timeful vs Whensdays
An honest comparison for picking a scheduling and availability tool - updated July 2026.
Timeful (formerly Schej) is a genuinely good availability poll: free, open-source, no login, and it can pull participants' Google or Outlook calendars straight into the grid. The hosted site is ad-supported, though, and where it stops is where the plan starts - Timeful finds the overlap, then hands the rest back to the group chat. Whensdays runs the same kind of poll and then runs the event too: RSVPs, the invite page, reminders, and the next occurrence.
Side by side
| Feature | Timeful | Whensdays |
|---|---|---|
| Free availability poll | Yes | Yes |
| No signup for guests | Yes | Yes |
| Open source | Yes | No |
| Ad-free pages | Ads on the hosted site | Yes - no ads on events, polls, or emails (sponsored GIFs can appear inside the optional GIF picker) |
| Calendar integration | Google, Outlook, Apple - pulls availability into the poll | Google + Apple - overlays your busy times on your availability |
| RSVP tracking + guest list | No | Yes - going/maybe/can't, visible to everyone |
| Event page (details, comments, photos, themes) | No | Yes |
| Email reminders + one-tap RSVP from email | Poll notifications | Day-before reminders, digests, one-tap RSVP |
| Schedule several winning dates as a series | No | Yes - RSVPs carry per date |
| Recurring groups (streaks, recaps, re-poll) | Availability groups | Yes - the group keeps meeting |
| Link previews with live "N in so far" | No | Yes |
The short verdict
Pick Timeful if you want an open-source overlap-finder - especially if everyone will connect a work calendar and all you need is the best meeting slot.
Pick Whensdays when the poll is for a real get-together: the winning times become scheduled dates with RSVPs, a shareable page, reminders people answer in one tap, and a group that plans the next one before the chat goes quiet.
