We strongly advise against deleting the app since reinstalling the app will delete all your artworks. One easy way to improve performance is to delete images from the All gallery. The All tab in My Profile displays published images that are also shown in the Published tab. If there are images in the All tab that you no longer desire to work on, simply delete them to enhance Colorfy's performance.
1. Tap on My Profile;
2. Select the All tab;
3. Tap on the image you no longer want to work on;
4. Tap Delete;
5. Confirm by selecting Delete.
