I am looking for an app that you can explain the shipping and the product with.
Its a little hard to explain but I need like 3 pictures on the homepage next to each other with a text below them.
Imagine the pictures to be icons of like the delivery guy delivering the package ...
And below I explain the steps.
Is there an app or another way for that?
You don't need an app to do this. It sounds to me like you just need to edit your theme. Here's a helpful Shopify support article.
