Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

Calculator· holds the better App Store score, 4.9 against 4.7.

UpkeepUpdate frequency

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.
