Verdict

The call

The clearest difference is in-app purchases: AstroPhoto LTE at none against Solar System Scope's 1. Solar System Scope's advantage is update cadence (every 4 months vs every 36 months) and iOS requirement (13.0 vs 16.2). On price, ads and device support there is nothing between them.
