Verdict
The clearest difference is update cadence: Calculator + at every 4 days against Basic Calculator's every 2 months. Calculator + also leads on review sentiment (85% vs 74%) and ratings volume (10K vs 3.2K). Basic Calculator's advantage is rating (4.8 vs 4.6). On price, ads, in-app purchases and monetization model 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 + sells 12 in-app purchases, starting at $4.99 per month and Basic Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Basic Calculator holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 10K and 3.2K respectively. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 74% of Basic Calculator's, so the app with the better star average is not the one people write more warmly about.
Calculator + ships an update every 4 days, Basic Calculator every 2 months. Both last shipped on September 23, 2026.
