iOS and Android are the two most popular mobile platforms, so developers like RobTop will most likely release app updates for other platforms at a later date, because they want to release as soon as possible to important platforms and Kindle Fire HDX isn't exactly major-league on the importance scale, as much as many players may be left behind. To be honest, many devs don't release all updates for this platform at all! If a platform like Fire HDX misses out on an update, it's only a minority loss.
