The clearest difference is review sentiment: Numbertopia at 100% against ClassIn's 51%. Numbertopia also leads on rating (5.0 vs 3.6) and in-app purchases (none vs 11). ClassIn's advantage is update cadence (every 11 days vs every 5 months) and ratings volume (1K vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. ClassIn sells 11 one-off in-app purchases. Numbertopia asks for nothing beyond the download.

Numbertopia holds the better App Store score, 5.0 against 3.6.
