Where each one falls short

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

FigJam

  • Organization and Enterprise tiers are billed annually only, with no monthly billing option
  • Free Starter plan caps AI credit usage at 150 credits per day and 500 per month, well below the 3,000 monthly AI credits on a Professional full seat

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.
