Verdict
The clearest difference is review sentiment: Amino Acid Quiz at 90% against Open eClass Mobile's 2%. Amino Acid Quiz also leads on iOS requirement (13.0 vs 15.3). Open eClass Mobile's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
