iOS: The Apps Dock is the most accessible bit of real estate on your iPhone. You can reach it from any page of the home screen, and it's never more than a single Home button press away (or a swipe up if you have an iPhone X). If you're like me, however, you've been criminally underusing the Dock by stocking it with single icons instead of a folder.

There's a lot going on in this screenshot (if you're wondering how to add blank space to your home screen here's a guide), but I want to focus on that folder in the dock. In this case, it's crammed full of messaging apps. So all your conversations are just a tap away at all times, whether they're happening in Facebook Messenger, Slack or Apple Messages.
You could apply the same idea to any type of app. Create a folder for all your social media icons and stick it in the dock. You could also do the same thing for all your news apps, or games.
There's one small trick to know when setting this up: You can't go the usual route of creating a folder by dragging one app on top of another if the second app is already in the dock. For some reason, that just doesn't work. Instead, you'll have to create a folder on the regular home screen first, open up a spot in your dock, and then drag your new folder into the vacant position.
Once that's done you'll have instant access to as many apps as you want instead of limiting yourself to just four.
