Verdict
The clearest difference is price: Star Exposure Calculator at Free against EXIFrame's $0.99. Star Exposure Calculator also leads on iOS requirement (13.0 vs 17.0). EXIFrame's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). On in-app purchases and device support there is nothing between them.
