What organizers say about Gumb
4.7/54.7 out of 5 stars271 ratings across both platforms25K+ users
Great app for scheduling. Very clear, reliable and easy to use.
Top product for organizing communities
We, an ice hockey club, have been using Gumb for many years. Top customer support and very stable.
I am an assistant coach of a U21 floorball team: great app for managing training attendance. I can export an attendance list at any time. If training is canceled at short notice, as an admin I can also send a push notification to everyone involved right away. Cool app... keep it up...👍
With all my hobbies I always had a big muddle. With the Gumb app I can see who is coming when, and I can also ask why not... The layout is very user-friendly and modern. I think the app is very good and recommend it.
Great app, works even for very large clubs. Highly recommended.
We tried out various apps in our club and Gumb covers our needs best! If you have questions, support helps right away. The app is constantly being improved and new, very useful features keep being added.
