# Calculator # vs Quadratic Equation AI Solver

The clearest difference is rating: Quadratic Equation AI Solver at 5.0 against Calculator #'s 4.6. Calculator #'s advantage is ratings volume (36K vs 2) and iOS requirement (12.1 vs 15.0). On price, update cadence, ads 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 Quadratic Equation AI Solver sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Quadratic Equation AI Solver holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 2, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
