The call

The clearest difference is in-app purchases: Astris at none against 3D Solar System Tour's 1. Astris also leads on ads (none vs shown). 3D Solar System Tour's advantage is update cadence (every 3 weeks vs every 3 months). On price, device support and iOS requirement there is nothing between them.
