September 10, 2023 (5:30 AM) - 📱 Android App Version 1.0.98

It's finally here! After nearly a year, we've released a major update for Android. This version includes around 40 technical changes, some you can see, while others work behind the scenes to improve things and resolve issues. The standout feature is definitely the new navigation bar at the bottom - the Tabbar. It's going to make the app much easier to use for everyone, especially newcomers who will now get a brief introduction with five pictures.

Here are the highlights:

🔹 New Tabbar: Quick and easy navigation at the bottom - find what you need in a flash!

🔹 Onboarding for New Users: Learn the app in just five simple steps. Want to skip? No problem!

🔹 Member Sorting: The sorting you do on the WEB version now applies to Android too.

And those are just a few of the 40+ technical updates. Stay tuned for more improvements in the future!


Sept 8, 2023 - Web Version

Added: 50 MB Document Uploads

We've got thrilling news! Now, you can upload documents up to 50 MB to our documentation platform, whether it's in the general folder, group folders, or within events. The performance remains top-notch, ensuring that when you access an event, downloading the associated document is superfast and seamless. A big thank you to the music associations that inspired us to make this improvement. Get ready for an enhanced documentation experience!

Added: Updated Privacy Policy – More Details Coming Soon.

Added: Fresh Website Look - We've given our website a fresh new look to enhance your user experience.

Added: Badges for Group Leaders - You can now spot badges for group leaders in planners and member lists, making it easier to identify them.

Fixed: PDF Downloads - You can now download large files, such as event details, for individual events.


Sept 1, 2023 - Web Version

Added: Pre-registering individuals

Admins can now pre-register new members directly via their email address - without the previous 24-hour limit for temporary passwords. When a new address is added, Gumb automatically sends an invitation with a password. Members can log in immediately and change the password if needed. Take advantage of this update and simplify your invitation process!


Fixed: PDF Download. You can now download the event details again for individual appointments.


August 30, 2023 - Web Version

Added: Easier password management for admins!

From now on, admins can effortlessly initiate "password reset" for their members. With just one click, the process starts, and the member quickly receives a link to conveniently reset their password to the email address on file. Please note: Unfortunately, this feature is not available for members using Facebook, Google, and Apple-Accounts. Instead, the member can continue to use the familiar login icon.


Fixed: Collapse / expand total count. The total number of response statistics for an appointment can now be expanded again.

Fixed: optimized user experience for sliders! We've reworked some sliders in the sidebar to ensure a smoother experience. No matter what browser you use, using these sliders will now be more pleasant and reliable.

Fixed: Faster loading times for report statistics! The statistics in the new "Attendance Control" report will now load faster using "Lazy Loading". Enjoy a smooth and snappy experience when browsing the data."


August 22, 2023 – Apple iOS App Version Number: 6.5

Added: After intensive negotiations with Apple (yes, they wanted 30% of the subscription fee!) we proudly present Version 6.5 of our Gumb iOS App! Here are the highlights:

🔹 New Tabbar: Fast and intuitive navigation right at the bottom. Find what you're looking for in a flash!

🔹 Onboarding for Newcomers: 5 quick steps to get you acquainted with the app. Want to skip? No problem!

🔹 Member Sorting: You're sorting on the WEB? Now visible on iOS too.

And these are just a few of over 50 technical updates. Stay tuned for more improvements! 🍏


August 17, 2023 - Web Version

Added: A big thank you to the Swiss J&S representatives for the great feedback on our new Attendance Report 📊. We officially launched it today and have made some improvements based on your input. Among other things, we've optimized the display and reduced loading times. Thanks for your support!


August 11, 2023 - Web Version

Added: In "My Appointments" in your profile, a dynamic icon awaits unanswered appointments. Unanswered appointments will be listed as "Awaiting" in the statistics. A filter for this will be available soon – stay tuned!

Added: Attendance lists at the touch of a button, no manual effort required → Gumb has integrated the innovative "Presence check" 📊 into the Statistics tab of the Scheduler. Simply select this report from the first drop-down menu. Thanks to collaboration with Swiss J+S leaders, it's specially designed for easy integration into the Swiss National Sports Database (NDS). Recording attendance data has never been easier!


July 28, 2023 - Web Version

Added: For browsers like Google Chrome, Firefox, etc., we have disabled automatic translation as it was causing display issues. If it still looks unusual, set the translator add-on to "Never translate this page" in your URL/address bar or browser settings.

Fixed: Various bugs, including display issues in Firefox, stuck in-app messages, and optimized Google Calendar connections.

May 9, 2023 - Web-Version

Fixed: Fixed a few bugs in the context of the "Group Leader" role (See more: Roles and permissions) - Group Leaders can now distribute nominations and penalties in their group (See more: What does the ⭐& ⚫ mean?).

Fixed: Group leaders can now edit past events (only in the assigned group).

Fixed: Sometimes when creating an appointment series with the "all day" option, 2 appointments were created instead of 1.

Fixed: a few minor UI fixes to the "tasks"

Fixed: Improvements when changing email address (change registered email address of user account).

Fixed: Some admins received error messages while receiving member "join community requests" during their trial subscription.


May 3, 2023 - Web-Version

Added: Your community's email function or email page is now responsive, meaning it will be usable and cleanly displayed on any device, including your smartphone. So from now on, use the web app on any device when you want to send an email.

Added: Sorting of group members → Admins and group leaders are always at the top of the "Scheduler" and "Scheduler-groups." Click on the group and go to the "Members" tab - use the slider to the left of the member to adjust the order. Note: For now, your changes will only be displayed in the web app and will only be synchronized on the two smartphone apps (iOS/Android) with the next updates. For example, to change the first or last names of your members, you as an admin can update the member profiles in the community settings ⚙️ or directly in each group by clicking on the pencil icon (🖊) on the right.


April 24, 2023 - Web-Version

Fixed: "Conversations" → finally fixed the "chat bugs" as well. In the web app, a group chat is now also available per group planner (see "Conversations"). Each community also has a "Main Chat". The smartphone apps (iOS and Android) will also continue to correct these bugs in the coming weeks.

Note: Gumb's chat feature is not currently part of Gumb's core functionality and requires funding that is not covered/available with current subscription costs. With new subscription plans (price changes), Gumb thus aims to cover further software development costs towards the end of 2023. Thereby also a free plan shall be developed, where especially small clubs (e.g., less than 6 members) could profit from a free version with fewer functions.


April 5, 2023 - Web-Version

Added: Download appointment schedules as Excel or CSV files! Now you can export your entire appointment list and we have completely redesigned the statistics page! The new report called 'Appointment Schedule" gives you an overview of facts and figures of your events. We are already working on another report called 'Member Figures," which will be related to user performance. The diary report is now available in the web app for all users. While administrators can view all data, members can only see the data of the dates they were activated/invited to.


Fixed: Your community's cover image is now displayed everywhere you share your community link. Note: Some apps reduce the quality or don't show the image at all.


Fixed: Fixed some minor bugs and link redirects. The bugs came about because we also optimized the web app for smartphones (iOS/Android) (with a simultaneous switch to TypeScript).


March 21, 2023 - Web version

Good news: Since January 19, we have been working hard to improve our platforms (Web, iOS, & Android). The result is something to be proud of: Our website (WEB app) and our apps for Android and iOS are now running faster and more stable than ever!

Fixed: During this time, bugs or improvements were made to the Community-Matrix (more about the Matrix). The Google Calendar connection has been stabilized. Fixed some minor bugs in scheduling when creating series.

Added: A plus sign (+) on the member list to open the member management faster and more directly (more about Invite members).

But that's not all. We also worked on a new design for the menu bar at the bottom of your smartphone (Tabbar). This will (hopefully) be released by May, but we can already tell you that it will be even more intuitive and user-friendly. This means for you (and all your members): easier and faster access to all our great and most important features!


Jan 19, 2023 - Web version

Added: More pages with TypeScript have been added. This to make the Gumb web version usable for smartphones and tablets. TypeScript is a scripting language developed by Microsoft based on the ECMAScript 6 standard proposals. It allows our software developers to better handle our code (software code). It also helps with future changes and improvements.

Added: More pages with TypeScript have been added. This to make the Gumb web version usable for smartphones and tablets. TypeScript is a scripting language developed by Microsoft based on the ECMAScript 6 standard proposals. It allows our software developers to better handle our code (software code). This also helps with future changes and improvements.

Fixed: For appointment series and selecting "All Day", the current day (the first in the series) could not be responded to. This now works again.

Fixed: Some minor bugs with appointment series, with the matrix and at the UI (interface) were fixed.


December 5 - new iOS version not yet approved.

Apple is currently doing a major verification, so the release of our new iOS version is delayed. This is very annoying because some bug fixes are pending and many of you are waiting for them. Apple has other requirements (for them to make money) that guidelines we have to adhere to. We are doing everything we can with Apple to successfully complete the testing as soon as possible. We thank you for your patience.


November 25, 2022

We have used November to simplify adding new members. When you click on "Add user", you will see a note with a brief description of how to invite new users to the community (Read more: Add new user).

The browser version (web app) has also been further optimized for mobile. This way, if the iOS or Android app does not work, members can also use the web version on their smartphone (open the Internet browser on the cell phone and enter

Added: When users log out of the app and enter their email incorrectly the next time they log in (for example, entering their name with uppercase letters instead of lowercase), Gumb now automatically converts everything to lowercase. Note: It actually happens "often" that users want to log in with an email that is not registered (→ Check whether via social media icon was logged in each time) or just unfortunately type incorrectly (→ Our tip: Always let login data saved, so delete app and install and then just save login data and allow notifications from Gumb!).

Added: Clickable mobile pushes - Clicking on the mobile push now takes you directly to the event (app opens directly and takes you to the answer selection).

Fixed: a few translation errors & minor bugs.


October 11, 2022 — Web-Version

Added: We are now gradually introducing TypeScript. TypeScript is a scripting language developed by Microsoft based on the ECMAScript 6 standard proposals. It allows our software developers to better handle our code (software code). This will also help with future changes and improvements. The first step is to make the Gumb web version usable for smartphones and tablets now. In doing so, numerous pages have to be coded or tackled individually. The main menu and planner views are already working.

Added: Document upload, table collapse function, spacing, and logic flows (members can no longer set a nomination/call-up for themselves).

Web Sockets for iOS (real-time updates) have been added. Before, you had to reload the page to see changes to members. Gumb will now display your response within a few seconds of responding to an event.

Added: Clickable links can now be added to event descriptions. From now on, you can also copy texts (hold text).

Added: Member profiles open as soon as you click on the profile photo. Furthermore, the event organizer is now clickable (note: if the user has his/her mobile number stored on Gumb, you can click on it and your iOS phone will call him/her directly).

June 29, 2022 — Web-Version

Added: "Step Functions" - Step Functions is a cloud service from Amazon Web Services (AWS) that allows our software developers to manage and visualize the components of distributed, more component applications. This feature has been added for event management (change event series). Previously, for event series with more than 50 events, there was sometimes a timeout error message - with Step Functions, the series will be updated in 2.7 seconds, error-free. We will extend this feature to more processes in the app / tool.

Added: Improved interface from own user profile and community home page (editing from your user-profile is now easier, automated line breaks, links are presently clickable and so on).

Added: The web version is not meant for a mobile phones, but on some devices it is partially opened automatically during the registration process.
