The short version

  • Only Stellarium has a free tier, so it costs nothing to try first.
  • Each has a real cost: Babbel the App Store listing for Babbel (seller of record: Babbel GmbH) states that subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, with payment charged to the buyer's Apple account; plans are sold in 1, 3, 6 and 12 month terms, and the listing itself discloses no price figure, so the actual monthly-equivalent cost is not visible without proceeding into a purchase flow.; Stellarium it is desktop-only software, so it has no native touch-optimised phone interface; the similarly named mobile app is a different paid product from a different company.
  • They diverge on capability: Babbel covers Bite-sized lessons, Stellarium covers Photorealistic sky rendering.
  • 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.

Babbel

  • The App Store listing for Babbel (seller of record: Babbel GmbH) states that subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, with payment charged to the buyer's Apple account; plans are sold in 1, 3, 6 and 12 month terms, and the listing itself discloses no price figure, so the actual monthly-equivalent cost is not visible without proceeding into a purchase flow.

Stellarium

  • It is desktop-only software, so it has no native touch-optimised phone interface; the similarly named mobile app is a different paid product from a different company.
  • As a volunteer-maintained open source project, support is community-based rather than a guaranteed commercial help desk.
  • The interface, while capable, is less immediately intuitive for a first-time user than a polished commercial phone app.
  • Telescope control and some advanced plugins require additional setup that a non-technical user may find fiddly.
  • Because it shares a name with the unrelated paid Stellarium Mobile Plus app, buyers researching pricing online can easily conflate the two products.
