In both the browser extension and mobile apps of the Phantom wallet, you can view the current list of featured apps (labeled as 'Sites' on iOS) by visiting Phantom's Explore section. To get here, first select the 🌐 icon along the bottom of your wallet view and then clicking on Apps ('Sites' on iOS).
The current list of featured apps will be shown in a carousel at the top of the Apps section of the explore tab.
These apps are hand selected by the Phantom team to showcase apps we think you would like. These could be currently trending popular, new, IRL events, safe airdrop links, etc...
You can find a new set of Featured Dapps on the explore page every week!
