iFont is an application available for Android smartphones and tables in which you are able to install a variety of fonts on your mobile device. Straight away, you can notice a friendly interface where many fonts are displayed. In case you want something specific, you can use the search function displayed at the top of the window. Inside the Recommended section, many fonts are shown and you can filter them based on language.
The great thing about this fancy app is that you can use it without having your phone rooted. This feature is limited to devices made by Samsung, Huawei, Xiaomi and Meizu. If your device is made by some other company, you'll need to have your smartphone rooted. You can customize aspects like font size. iFont comes with automatic backup feature which creates a copy of your default factory font.
This helps a lot in case you're not pleased with the third party fonts and you want to revert to default style. Inside the My tab you can check lists containing your downloaded and installed fonts.
