Afforess (original creator) has been DoS (i.e. unwelcome) for three years, and current gatekeeper Eluvatar has been promoted to admin and is thus unlikely to make any further substantial developments to NS++ for the foreseeable future (but then again, I'm not Elu's super-sekrit puppet, so hell if I know). When iOS doesn't even have an equivalent to Stately (the unofficial Android app), you shouldn't expect NS++ on your Apple-brand mobile device any time soon.
