You can increase (or decrease) the font size with one touch.

This is a simple app that increases the font size of text with one tap.

This is useful when you want to quickly show the screen to someone.

If you paste the included widget on your home screen and use it by tapping it, you can really switch between 100% and 200% with one tap.

[What is a widget? ]

Usually, when you install an app, a small button with a picture called an ``icon'' is created on the home screen, and you can tap this to launch the app. In other words, the "app launch button" is an "icon." Conversely, an icon is a button that can only launch an app (open a screen).

"Widgets" are also parts that can be added to the home screen just like icons, but unlike icons, you can change the color and picture and do various things with them.

FontBig has a widget that allows you to ``change the font size suddenly without opening the app screen'' with just a tap.

Find the add widget menu in the menu of your home screen app, select the FontBig widget, and paste it on your home screen. From now on, you can change the font size with one touch just by tapping this widget. Become.
