We are constantly monitoring Color By Number's performance to grant your relaxation as you create your artworks. However, there are specific conditions that may cause the app to perform below our expectations and standards.

We strongly advise against deleting the app since it will delete all your artworks.

Cleaning up your device's storage can improve the app's performance. Deleting apps you don't use anymore, and erasing images, videos, and large files can open up some space for the app.
Also, make sure you secure a stable internet connection while using the app.
