Verdict

The call

The clearest difference is review sentiment: Calculator· at 84% against Calculator +ㅤ's 47%. Calculator· also leads on monetization model (free with in-app purchases vs subscription) and rating (4.9 vs 4.6). Calculator +ㅤ's advantage is update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.
