I'm looking for advice from VoiceOver users about what they would expect from an equation-editing app.
I am an app developer designing an equation-editing app for iPhone, iPad and Mac. Think Microsoft word but for creating and editing equations. It will be an app rather than a plug-in. However, it will be easy to share equations to include them in documents in other apps like Microsoft Word or export them as LaTex. My new app will not solve equations but can be used to create and edit equations. I have made one previous VoiceOver-optimised app so I have some experience.
What should I be concentrating on to ensure easy use with VoiceOver in an equation-editing app?
