As per Statista, Google Play Store had well over 2.6 million apps as of June 2022. With this many applications at your disposal, it wouldn’t be surprising if you have two, or even three, of the same kind of apps. You probably have more than one browser, for example, and possibly multiple file explorers, calendars, and even audio players on your phone.
Yes, not every app is exactly the same, as some have distinct features that separate them from the crowd. You might have a note-taking app that’s good for to-do lists and another note-taking app that allows you to export the note to a PDF. While both are the same at the core, they offer you varying functionalities. In cases like this, it makes sense to keep both apps on hand.
However, if you have too many redundant apps on your phone, they will eventually slow your device down. It’s always a good idea to pick which of your similar apps you like best and uninstall the others.
