Third party keyboards have given iOS users the ability to use customized keyboards across apps. Until recently, the powerful Co:Writer word prediction had been locked within it’s own app limiting the user’s ability to use the support on any app. With a recent update, Co:Writer Universal now provides a 3rd party keyboard option giving writers the ability to use this support across any app (Notability, Notes, Google Docs, Safari, etc).
The settings for auditory feedback carry over from the Co:Writer app as well as the topic dictionaries created. These can be toggled on and off directly within the keyboard.
This is a great and well needed update! For more information on how to enable 3rd party keyboard see this Apple support documentation.
