Verdict
The clearest difference is review sentiment: CATQR Class Attendance Tracker at 100% against Three's 18%.

Three's advantage is update cadence (every 2 weeks vs every 12 months) and ratings volume (1.1K vs 15). On price, in-app purchases, device support and iOS requirement there is nothing between them.
