Verdict
The clearest difference is ads: Calculator 3.0 at none against Calculator·'s shown. Calculator 3.0 also leads on update cadence (fortnightly vs every 3 months) and monetization model (free vs free with in-app purchases). Calculator·'s advantage is review sentiment (84% vs 66%) and rating (4.9 vs 4.7). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculator 3.0 sells 3 one-off in-app purchases and Calculator· sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Calculator· holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Calculator· has 34K ratings behind it against 3.5K, so its average is the more settled of the two. Written reviews point the same way: 66% of Calculator 3.0's written reviews are positive against 84% of Calculator·'s.
Calculator 3.0 ships an update fortnightly, Calculator· every 3 months. The most recent releases landed on October 17, 2026 and October 20, 2026 respectively.
