# xGeometry vs Pythagoras Calculator

The clearest difference is rating: Pythagoras Calculator at 4.6 against xGeometry's 2.7. Pythagoras Calculator also leads on review sentiment (83% vs 64%) and update cadence (every 4 weeks vs every 2 months). xGeometry's advantage is in-app purchases (none vs 8) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Pythagoras Calculator sells 8 one-off in-app purchases. xGeometry asks for nothing beyond the download.

Pythagoras Calculator holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Pythagoras Calculator has 248 ratings behind it against 35, so its average is the more settled of the two. Written reviews point the same way: 64% of xGeometry's written reviews are positive against 83% of Pythagoras Calculator's.

xGeometry ships an update every 2 months, Pythagoras Calculator every 4 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
