More info. Apparently Android too. Still waiting for it to show up in App Store, and also Google Play.
(I do wonder if it would be better to have a ‘Kindle apps’ sub-forum here rather than discuss in respective ‘Apple devices’ ‘Android Devices’ ‘Windows devices’ etc forum as seems to be the convention. One-stop shopping instead of having to discover threads buried in multiple forums.)
