When you flip through the screens of your phone, you most likely see each app as a little icon. But some applications let you swap that icon for a widget—a larger image that sometimes lets you access the app without opening it. Widgets add aesthetic appeal to your home screens while also providing some useful features. For example, weather apps can deck out your home screen with the day’s up-to-date temperatures, music players might let you skip songs or hit pause, and memo apps can display prominent notes. 1Weather is free with ads or $2 without ads.
