Timeful vs WhenIsGood

Timeful

• Groups choosing a meeting time without anyone creating an account
• Respondents who want to fill in availability from their own calendar
• Organizations that want to self-host an open-source scheduling poll

WhenIsGood

• Organizers who want an availability poll with no sign-up and no adverts
• Groups in different time zones choosing a time for a call
• One-off meetings and events where invitees should not need accounts

Timeful

• It runs in a web browser only; the site links to no desktop or mobile apps.
• Email notifications, reminders and showing responses only to the event creator all require signing in.
• Connecting Apple Calendar means generating an app-specific password for your Apple ID and entering it in Timeful.
• Availability groups, which track members' weekly availability, read it from Google Calendar only.

WhenIsGood

• Event links have no passwords; the FAQ relies on the random invitation URL being hard to guess.
• The FAQ describes calendar integration only as an iCal (.ics) export of the chosen time, so availability is entered by hand.
• Without an account, you need the results code from the event-created page to see responses later.
• The site text is in English only; the language box changes how dates, times and numbers are written.

Timeful

Availability polls

Create an event with a range of dates and times, share the link, and see where everyone's availability overlaps. The home page says no login is required, and the FAQ puts no limit on respondents.

Calendar autofill

Respondents can fill in their availability from Google Calendar, Outlook, Apple Calendar or an ICS feed URL. Other people see only the availability entered, not the calendar events.

Available and if-needed times

A respondent can mark a slot as available or as possible only if needed, and the results can show when a chosen subset of the group is free.

Time zone conversion

Times are converted to each viewer's local time zone, and a selector at the bottom of every poll lets a viewer switch zones by hand.

Email notifications and reminders

A signed-in organizer can be emailed on each response or after a set number of responses, and can send reminders on the day an event is created, one day later and three days later.

Open source and self-hosting

The code is on GitHub under the AGPL-3.0 license, with a deployment guide for Docker Compose and NixOS and a plugin API for reading and setting availability from a browser plugin.

WhenIsGood

Paint-the-grid event setup

Click the grid for the dates and times you propose, optionally name the event, and press Create Event to get a link for invitees and a results code for yourself.

Results with near misses

Times that suit everyone show in green, and near misses carry red dots for the people who cannot make them. Respondents are listed from most flexible to least flexible.

Adjustable slots and hours

Buttons switch the grid between 15-, 30- and 60-minute slots or whole days, and the options panel widens the hours beyond the default 8am to 6pm.

Time zone support

With time zones switched on, proposed times are adjusted to each invitee's own zone, and the results page produces text showing the chosen time for every invitee.

Optional account and dashboard

Logging in with an emailed six-digit code, with no password to choose, collects your events and responses on a dashboard so results codes do not have to be kept.

Email alerts and iCal export

An organizer can ask for an email whenever someone responds. Clicking the chosen time on the results grid gives an iCal (.ics) link to add to a calendar or attach to an email.
