# Calculator⁼ vs FactorCat

The clearest difference is ads: FactorCat at none against Calculator⁼'s shown. FactorCat also leads on rating (5.0 vs 4.6). Calculator⁼'s advantage is ratings volume (358K vs 1) and update cadence (monthly vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Calculator⁼ sells 8 in-app purchases, starting at $0.49 per 7 days and FactorCat sells 2 in-app purchases, starting at $12.99 per year. Whichever you choose, the download price is not the number that matters.

FactorCat holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator⁼ has 358K ratings behind it against 1, so its average is the more settled of the two.

Calculator⁼ ships an update monthly, FactorCat every 3 months. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
