Tabs won't close [iOS UI]

[hello-smile6]

I have struggled using the interface because the tab close button doesn't work. Additionally, the app appears to be a web-based interface, as the Save Image and Copy buttons appear upon pressing and holding an image. Please resolve this so I can play easily.

Interfaces to improve UI for:

• iOS
• Android
• Windows
• MacOS
• Other applicable interfaces, such as a web app
