Verdict

The call

The clearest difference is ads: CALC Smart Calculator ± at none against iCalc's shown. CALC Smart Calculator ± also leads on ratings volume (2.4K vs 38) and rating (4.8 vs 4.6). iCalc's advantage is update cadence (every 6 days vs fortnightly) and review sentiment (100% vs 87%). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. CALC Smart Calculator ± sells 4 in-app purchases, starting at $0.99 per 3 months and iCalc sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

CALC Smart Calculator ± holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: CALC Smart Calculator ± has 2.4K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 87% of CALC Smart Calculator ±'s written reviews are positive against 100% of iCalc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CALC Smart Calculator ± ships an update fortnightly, iCalc every 6 days. Both last shipped on September 22, 2026.
