Verdict
The clearest difference is ads: Light Planner at none against Star Exposure Calculator's shown. Star Exposure Calculator's advantage is update cadence (every 2 weeks vs every 15 months) and iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
