# iCircuit vs Calculator ∞

The clearest difference is rating: Calculator ∞ at 4.7 against iCircuit's 3.8. Calculator ∞ also leads on price ($5.99 vs $12.99) and ratings volume (6.4K vs 142). iCircuit's advantage is update cadence (every 4 weeks vs every 2 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

iCircuit costs $12.99 and Calculator ∞ $5.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month and Calculator ∞ sells 4 in-app purchases, starting at $3.49 per month. Whichever you choose, the download price is not the number that matters.

Calculator ∞ holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Calculator ∞ has 6.4K ratings behind it against 142, so its average is the more settled of the two. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 75% of Calculator ∞'s.

iCircuit ships an update every 4 weeks, Calculator ∞ every 2 months. Both last shipped on October 29, 2026.
