The app works in every social app, so you can use it directly on Instagram, Facebook, YouTube, Snapchat, WhatsApp, TikTok, and more.

One of the best things about Font Keyboard is the wide range of fonts available. You can browse through dozens of fonts or create your style. The app is easy to install and comes with a simple three-step installation process. Once installed, you're all set to use the app and add a little style to your social chats.

It's worth noting that Font Keyboard is completely free to use with limited fonts.
