timeup.io focuses on the finding of the best fitting time spots for all event participants. On other platforms the event creator usually determines at which time slots an event should take place. Mostly, these time slots are the ones only the event creator can attend. So there is always a shift to inaccuracy. In addition, the design of timeup.io is very clean and intuitive. This allows an event creator or participant to be extremely quick on the creation or join process.
