Verdict
The clearest difference is in-app purchases: Protein Sequence Viewer at none against QuizAI's 2. Protein Sequence Viewer also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). QuizAI's advantage is ads (none vs shown). On price and update cadence there is nothing between them.
