Ionic Apps and ADA Compliance

Has anyone ever had to make sure their app was ADA compliant or was compatible with services like VoiceOver on iOS for those whom want to use your app and may be visually or hearing impaired.

I wasn’t sure if there were any Ionic/Cordova plugins to help with something like this, or an extension to the existing Ionic Framework that would help solve some of these issues.

Thanks for any information or direction.
