Group planning together

In short

Gumb is a shared calendar for every group that plans together: circles of friends, project groups, temporary teams and every group that fits no box. Unlike a shared calendar, Gumb shows on every event who said yes or no, sets response deadlines, hands out tasks and sends push reminders. If you like, you also see the events in Google, Apple or Outlook.

More than a shared calendar

FAQ: the shared calendar app

How is Gumb different from a shared Google Calendar?

A shared calendar only shows the event. Gumb also shows who said yes or no, sets response deadlines, hands out tasks on the event and sends push reminders.

Can I see Gumb events in Google, Apple or Outlook?

Yes. Google has a direct connection, Apple and Outlook an iCal link. New and changed events flow from Gumb into your calendar, not the other way round.

Can I respond from my own calendar?

Yes. Synced events contain direct links to say yes or no.

How does everyone learn about a change?

After you edit an event, Gumb asks whether everyone should be notified. Push notifications arrive even when the app is closed.

Can I create recurring events?

Yes. Events repeat daily, weekly, monthly or custom, with a response deadline if you like.

Who can create events?

Owners and admins manage the whole community, group leaders schedule for their group. Members respond to events.
