I wanted to create a fake e-commerce app for the fictional store in the TV Series Chuck which is why it has a colour scheme from 2007. The main feature of this app is the tap and hold menu. 

After studying how people hold their phones and how big phone screens are, I thought the best way to utilise the menu system. I have got rid of the menu bar at the bottom of the screen, in favour of a "tap and hold" anywhere on the screen function. This allows for the user to hold the phone in the same position and control the whole menu from one finger. This also helps people with small hands or use a pop holder. This stops the user from always having to re-adjust their hand postion if they want to search for a product or use the menu bar. Having this feature creates more screen space so elements are better spaced apart from each other, making it easier to read and see.

In the demo below, the small red cross is a click or tap function due to adobe xd not having a tap and hold feature. (there is a secret hidden in the demo for Chuck Fans)
