# Calculator + vs Chippy Tools

The clearest difference is ads: Chippy Tools at none against Calculator +'s shown. Calculator +'s advantage is review sentiment (85% vs 55%) and ratings volume (10K vs 905). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Chippy Tools sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.5 for Chippy Tools. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 905, so its average is the more settled of the two. Written reviews are what separate them: 85% of Calculator +'s written reviews are positive against 55% of Chippy Tools's.

Calculator + ships an update every 4 days, Chippy Tools every 8 days. Both last shipped on September 24, 2026.
