Confession time: I barely leave the first page of my iPhone's home screen. No, my iPhone isn't very well organized and I don't limit the number of apps I download (trust me, this phone is a mess). The truth is, you don't have to rely on your iPhone's home screen pages to find and open an app. In most cases there is simply a much faster way.
The secret? Just swipe down on the home screen. This gesture activates Search, an underestimated, yet very powerful iOS tool. Here you can search for any app on your iPhone and start it, regardless of which start page it is on or how deep it is in a folder. You may even find the app you're looking for via Siri Suggestions under the search bar. There are four apps by default. However, if you tap "Show More", the number increases to eight.
One of my favorite features of this feature is that quick action menus still work for apps, after you are looking for and for apps in Siri Suggestions. That means you can access the story camera in Instagram with 3D Touch or Haptic Touch or start a new tweet in Twitter without ever knowing where these apps are located.
