Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
