A free app for Android, by Nima Nahavandi.

Elevate the look of your Instagram feed. With the Fonto – Story font app, you can create beautiful stories with various fonts and backgrounds. It has a very easy-to-use interface, so you can use it even if you have no prior knowledge of coding. The best thing about this app is that it is free, so you do not have to pay a penny to download it. 

To create a story, select a font and enter a caption. You will then be able to save it in your gallery. Once you are done creating your stories, you can select them and share them on your social media accounts.
