The short version

  • Only Khan Academy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Khan Academy the Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.; SkySafari the three tiers are separate purchases, so upgrading from Basic to Plus or Pro later means buying again rather than paying the price difference.
  • They diverge on capability: Khan Academy covers Video lessons, SkySafari covers Tiered editions.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Khan Academy

  • The Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.

SkySafari

  • The three tiers are separate purchases, so upgrading from Basic to Plus or Pro later means buying again rather than paying the price difference.
  • Even the Basic tier costs more than a comparable free or freemium app like Star Walk 2 for a casual user.
  • Telescope control only works with compatible motorised mounts, so it is useless to someone with a manual telescope or no telescope at all.
  • Pricing fluctuates with frequent promotional sales, so the list price is not a reliable guide to what most buyers actually pay.
  • The interface, particularly on the Pro tier, has a steeper learning curve than a simple AR sky map app aimed at casual users.
