FontRapid is a free Sketch plugin, helps designers create professional OpenType fonts with ease directly in Sketch app. The output font can be used for print, web and mobile, and sold to anyone with no limit (both free and commercial use).
I just used it quickly after finding it here on PH. Love it for inspiration, but would probably be a little limiting if you want to do something more serious.
- Easy to use and get started.
- Very basic functions
- Not all settings stored on save
