In short
Gumb is a volunteer app for social organizations, NGOs, animal welfare, environmental groups, parent councils and political groups. Activities, meetings and campaigns sit in the calendar as events, volunteers sign up by the response deadline, and single tasks such as rides, shifts or material are handed out right on the event. Projects and sites plan in their own group schedulers, and members never pay, the organization covers the subscription.
