Verdict

The call

The clearest difference is monetization model: Scientific Calculator at free with in-app purchases against Calculator +ㅤ's subscription. Scientific Calculator also leads on rating (5.0 vs 4.6) and review sentiment (67% vs 47%). Calculator +ㅤ's advantage is ratings volume (4.6K vs 5) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.
