# Calculator + vs Amazing Calculator

The clearest difference is ads: Amazing Calculator at none against Calculator +'s shown. Amazing Calculator also leads on rating (5.0 vs 4.6) and monetization model (free vs free with in-app purchases). Calculator +'s advantage is update cadence (every 4 days vs every 51 months) and ratings volume (10K vs 5). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Amazing Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Amazing Calculator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 85% of Calculator +'s written reviews are positive against 100% of Amazing Calculator's.

Calculator + ships an update every 4 days, Amazing Calculator every 51 months. The most recent releases landed on September 24, 2026 and June 5, 2026 respectively.
