What Timeful is
Timeful is a free browser-based tool for coordinating group meetings. An organiser creates an event, shares its link, and views where participants’ availability overlaps. It provides scheduling links and two-way calendar sync. Timeful says it integrates with calendars, and its maker describes Google Calendar availability autofill. Participants can enter or adjust availability manually and can complete an event without signing in with Google; Google and Outlook sign-in are available. Listed event options include date-only polls, showing availability for only a subset of participants, and hiding responses. Optional email notifications can be sent when people join an event. The maker describes event creation and shared links as optimised for mobile use, although the listed platform is web and no mobile apps are provided. Timeful’s code is described as fully open source, with a GitHub repository linked. The maker says it was founded in 2023 by high school friends Jonathan Liu and Tony Xin, with Lesley Moon joining later. Its Free plan costs nothing and requires no login.
