Verdict

The call

The clearest difference is price: Calculator´ at Free against Pascal's $2.99. Calculator´ also leads on rating (4.6 vs 4.0) and ratings volume (478 vs 23). Pascal's advantage is update cadence (every 2 weeks vs every 5 weeks). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
