Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Labster
- Customization is limited and labs cannot be easily adapted to specific course learning outcomes
- Simulations can lag or freeze depending on operating system and connection speed
- Cannot fully replace hands-on physical lab experience and data collection
- Students report preference for tactile physical lab experience over virtual simulations
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.
