Does it work on iPhone 7 or I need iPhone X and higher?

Great job! You can hide dock and use Touch Bar instead. And get more screen space. But actually this approach is not effective for me( I need to look at touch bar and slide it to get required app. It's much more faster to click on app icon in dock. Pros: Looks pretty) Cons: You can add customisation to add just required apps instead of all dock content. Now it's not easy to scroll touch bar...
