How do you check if an app installed?

I want to make an app gallery, so I need to check is another app installed. How to do that?


maybe this extension can help you:

I can't open that link

It works here

I will try to connect to wifi later

Check the Activity Starter docs. There might be a block for that.

The extension works, there is no problems
