# Mathway vs Pythagoras Calculator

The clearest difference is ads: Pythagoras Calculator at none against Mathway's shown. Pythagoras Calculator also leads on review sentiment (83% vs 51%) and iOS requirement (15.0 vs 17.0). Mathway's advantage is ratings volume (425K vs 242) and rating (4.9 vs 4.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mathway sells 8 in-app purchases, starting at $9.99 per month and Pythagoras Calculator sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mathway holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Mathway has 425K ratings behind it against 242, so its average is the more settled of the two. Written reviews complicate that: 51% of Mathway's written reviews are positive against 83% of Pythagoras Calculator's, so the app with the better star average is not the one people write more warmly about.

Mathway ships an update every 4 weeks, Pythagoras Calculator every 3 weeks. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
