# SnapCalc vs Pythagoras Calculator

The clearest difference is review sentiment: Pythagoras Calculator at 83% against SnapCalc's 25%. Pythagoras Calculator also leads on ads (none vs shown) and rating (4.6 vs 4.2). SnapCalc's advantage is ratings volume (41K vs 242) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. SnapCalc sells 9 in-app purchases, starting at $1.99 per 7 days and Pythagoras Calculator sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Pythagoras Calculator holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: SnapCalc has 41K ratings behind it against 242, so its average is the more settled of the two. Written reviews point the same way: 25% of SnapCalc's written reviews are positive against 83% of Pythagoras Calculator's.

SnapCalc ships an update monthly, Pythagoras Calculator every 3 weeks. The most recent releases landed on September 29, 2026 and September 26, 2026 respectively.
