I don't think there is a limit on number of "uicontrols" but there are few limitations:
1. Performance: App Designer performance may be affected when dealing with a large number of components or complex apps. It is recommended to keep the number of components and the complexity of the app within reasonable limits for optimal performance.
2. Memory Usage: App Designer apps consume memory, and the amount of memory required depends on the size and complexity of the app. Large apps with many components and extensive data processing may require more memory.
3. Graphics Rendering: App Designer uses the MATLAB graphics system to render components and plots. The performance of rendering graphics can be affected by factors such as the complexity of the plot, the number of plots, and the available system resources.
These limitations are important to consider when designing and developing apps in App Designer. It is recommended to test and optimize your app's performance and memory usage, and to keep the design and functionality within reasonable limits to ensure a smooth user experience.
Hope this helps!
