Verdict
The clearest difference is review sentiment: CAGR Calculator at 100% against Protractor+'s 15%. CAGR Calculator also leads on rating (4.7 vs 4.1) and iOS requirement (13.0 vs 17.6). Protractor+'s advantage is update cadence (every 2 months vs every 20 months) and ratings volume (10K vs 32). On price, ads, in-app purchases and monetization model there is nothing between them.
