I never used to have a system for managing my mobile apps. I believe that sloppiness spilled over into other areas of my life. My plan now: put the 16 most used apps on the home screen. The remaining apps then go in well-organized subfolders (e.g., productivity, finance, travel, etc.) on the second and third pages.
Note: I once saw a friend label her folders with mantras. For example, Fitness becomes “I am fit.” Travel becomes “I am well-traveled.” Building identity, while staying organized. Love that.
