# Calculator + vs Calculator!

The clearest difference is price: Calculator + at Free against Calculator!'s $0.99. Calculator + also leads on update cadence (every 4 days vs every 3 months). Calculator!'s advantage is ads (none vs shown) and rating (4.8 vs 4.6). On review sentiment, ratings volume, in-app purchases and monetization model there is nothing between them.

Calculator + is free to download; Calculator! costs $0.99 up front. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Calculator! sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calculator! holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 10K and 4.3K respectively. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 83% of 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, Calculator! every 3 months. The most recent releases landed on September 26, 2026 and September 27, 2026 respectively.
