Number Builder Update Notes: September 24, 2025
We’ve added commenting and a whole lot more to Number Builder as part of this week’s update.

Some new updates to Number Builder have just dropped, improving on our recent overhaul of your favorite free number-designing app.
New
- Commenting has been added on Showroom projects! Share your encouragement and leave a nice note for your favorite authors.
Improved
- A confirmation message is now shown when you delete a project successfully.
- The appearance of items in Private projects has been updated to show information in a cleaner and clearer way.
- Links to member profiles from Showroom detail pages are smoother and do not result in the entire page reloading.
- Adjusted the appearance of the posted and last modified dates of Showroom projects to avoid awkward text breaking.
- Updated the appearance of Showroom quick-preview to make better use of space, particularly on smaller screens.
Fixed
- Fixed an issue where the number preview could spill out of the preview window.
- Fixed an issue where a horizontal scrollbar could appear on some small screens on Showroom detail pages.
- Fixed an issue where the Favorites list would load a blank pop-up when logged-out. (Favorites are only viewable to logged-in members.)
- Fixed an issue where imported projects without outlines were adding an outline when opened in the Builder view.
- Fixed an issue where remixed projects could have been exported as JSON data, which would not include original author data.
- Fixed an issue where draft projects were not importing their titles properly after exporting.
As always, we hope you enjoy these Number Builder updates! We’re proud to keep Number Builder a free app for all iRacers, and we appreciate the Trading Paints Pro members whose memberships support our independent team. Thank you! 🏁
