The Deft response block supports the Moodle App. Most features are usable from the official app as well as a browser.
The Deft response block has support for the Moodle Mobile App. The block will be displayed in the app, users can post comments and make choices or polls in the app. Venues are displayed as links that will open in a browser currently. The block should work out of the box which the standard Moodle App or your own branded version without any added effort. However, the Mobile Apps only displays blocks that appear on the main course page, not on activity page. App users will only be able to access a Deft response block only if it appears in a course context.
The block also functions normally in a standard Mobile browser on Mobile devices.
