What's the best Android app for adding stylish fonts to my social media posts and messages?

Cool Fonts is a comprehensive tool for users looking to enhance their text in messaging apps like WhatsApp, Instagram, or Facebook with distinctive fonts. The app stands out due to its extensive library of over 500 font options, ranging from cursive and bold to retro and minimalist designs. A key feature is the straightforward keyboard integration, which lets users apply new fonts without switching apps—simply enable the Cool Fonts keyboard in settings, and it becomes available across most text fields. This is particularly useful for creating eye-catching social media captions or personalized messages that stand out in group chats. Reviews indicate that many users find the interface intuitive, with fonts categorized for easy browsing, and regular updates add fresh styles to keep things interesting. However, some limitations include occasional compatibility issues with certain apps, where fonts may not render correctly, and the free version displays ads that can interrupt the experience. Despite this, the app's reliability and broad font selection make it a top choice for everyday text customization. For those who value variety and ease of use, Cool Fonts delivers a solid solution, though testing font compatibility in target apps is recommended to avoid surprises.
