Large Icons Widget - Big Icons is a free tool for resizing app icons. It’s the perfect app for users who struggle with tapping smaller icons or those who have poor eyesight. Adding your own custom icon is not possible here, though. 

Has a tutorial

Upon opening the app, users are presented with a brief introduction to the program as well as a tutorial on resizing icons. To get started, tap and hold the home screen, touch Widget, and select the Large Icons Widget - Big Icons app. 

Then, choose an app and resize it as you want. Of course, you also have the freedom to remove or stack resized apps. Though it gets the job done with no fuss at all, the lack of customization features makes this app boring to use.

Straightforward and practical, Large Icons Widget - Big Icons works well as intended. It even includes a tutorial to help you get started. While it doesn't focus on customization, the app’s strengths lie in its functionality and hassle-free operation, as well as the benefit it provides people who have vision problems.
