For all who are looking for an extremely similar version on Android, type in "Outliner Alfred Fritz" in the android Playstore. I've been using it for years and it's also awesome with most of the same features. It syncs with Google Tasks, so you can also use it on your desktop computer. You can also use it with the BlueStacks Android emulator for Windows and it works extremely well there too : )
