# The Calculator Pro· vs Calculator⊕

The clearest difference is ads: The Calculator Pro· at none against Calculator⊕'s shown. The Calculator Pro· also leads on ratings volume (153 vs 9) and iOS requirement (10.0 vs 14.0). Calculator⊕'s advantage is rating (5.0 vs 4.5) and update cadence (every 10 days vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. The Calculator Pro· sells 1 one-off in-app purchase and Calculator⊕ sells 7 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Calculator⊕ holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: The Calculator Pro· has 153 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 81% of The Calculator Pro·'s written reviews are positive against 100% of Calculator⊕'s.

The Calculator Pro· ships an update every 3 months, Calculator⊕ every 10 days. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
