Currently Facebook doesn’t support formatted text posts! However, Facebook allows ‘special characters’. There are websites and apps that you can use to create special characters as a workaround, and there are font keyboards and websites available that can generate styled text for you. You can then copy and paste that text into your CinchShare message, and Facebook will keep the formatting when it is posted!
For desktop: One that we have heard that people like and is free, is https://coolfont.org.
For mobile phone: The FONTS app for the iPhone is another one many users like to use to create formatted text to copy/paste into CinchShare.
If Facebook ever expands their programming to fully include formatted text, we would certainly work to include that functionality within CinchShare!
