Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Skoolur
- Covers Classes 1 to 10 only, so students entering Classes 11 and 12 must move elsewhere at exactly the point pressure peaks
- Group classes mean less individual attention than one-to-one, which costs substantially more
- Live scheduled classes require fixed weekly availability, unlike self-paced platforms
- Priced per subject per month, so a student needing several subjects sees the total rise quickly
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.
