Verdict

The call

The clearest difference is in-app purchases: Solar Orrery at none against RealTime Space's 1. Solar Orrery also leads on iOS requirement (15.0 vs 26.0). RealTime Space's advantage is update cadence (every 2 weeks vs every 3 weeks). On price, ads and device support there is nothing between them.
