I was just doing some research on what font formats are provided with each type of licence today (desktop, web, app). It would be great to simplify things for users and send just the font format that is needed. It seems quite clear that otf and woff2 make the work for desktop and web (with some exceptions) but I still have doubts about the app license. App developers I’ve worked with asked me for ttf files some time ago but, if I am not wrong, otf files make the work as well. What font format do you provide users that buy app licences? Only ttf? Only otf? Both?
Looking forward to hearing your thoughts and comments on this. Thanks!
