Verdict
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.
