Where each one falls short

Pluralsight

  • No free tier, only 10-day free trial
  • Trial excludes lab and sandbox features on lower tiers
  • Core Tech plan at $45/month is most expensive option

Sky Guide

  • It is iOS-only, unlike SkySafari which also covers Android and desktop.
  • It has moved from one-time purchase to a subscription model, and long-time users who paid once for earlier versions have criticised the change publicly.
  • Pro tier pricing is high relative to Star Walk 2 for broadly similar core stargazing functionality.
  • It has no telescope control, unlike SkySafari Plus and Pro, which limits it to naked-eye and camera-based observing.
  • Its relationship to other apps under the same distribution platform is not clearly documented, which makes long-term support commitments harder to assess.
