No theory required to start: listen, play, repeat.

Verdict
The clearest difference is in-app purchases: DoReQuiz at none against CC Harp's 2. DoReQuiz also leads on update cadence (every 4 days vs every 4 months). CC Harp's advantage is iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
