The clearest difference is review sentiment: NTK IGCSE Biology at 100% against Past Code's 50%. NTK IGCSE Biology also leads on iOS requirement (8.0 vs 14.0). Past Code's advantage is rating (4.0 vs 3.0) and update cadence (every 6 days vs every 13 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Past Code holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 2 and 4 respectively. Written reviews complicate that: 100% of NTK IGCSE Biology's written reviews are positive against 50% of Past Code's, so the app with the better star average is not the one people write more warmly about.
