# Calculator # vs Omega Calculator

The clearest difference is ads: Omega Calculator at none against Calculator #'s shown. Omega Calculator also leads on review sentiment (83% vs 60%). Calculator #'s advantage is ratings volume (36K vs 44) and iOS requirement (12.1 vs 15.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and Omega Calculator sells 1 one-off in-app purchase. 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 4.7 for Omega Calculator. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 44, so its average is the more settled of the two. Written reviews are what separate them: 60% of Calculator #'s written reviews are positive against 83% of Omega Calculator's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
