Sometimes we install way too many apps and never get around to using them very much. This can lead to unnecessary notifications and other distractions that you’re much better off without.
Here's how to find out how many apps you have installed:
Open your iPhone’s Settings > General > About
Next to Applications you'll see the number of apps you have installed on your phone. Yikes!
What to do next
Use the Focus Lock to pull your apps out of their folders and begin uninstalling apps that don’t matter to you. You’ll feel a lot better when you do this exercise!
