# Genetic Code vs Biology Knowledge Quiz

The clearest difference is rating: Biology Knowledge Quiz at 4.7 against Genetic Code's 4.0. Biology Knowledge Quiz also leads on ratings volume (157 vs 6) and update cadence (every 3 weeks vs every 2 months). Genetic Code's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Biology Knowledge Quiz sells 7 in-app purchases, starting at $3.99 per 7 days. Genetic Code asks for nothing beyond the download.

Biology Knowledge Quiz holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Biology Knowledge Quiz has 157 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 55% of Genetic Code's written reviews are positive against 43% of Biology Knowledge Quiz's, so the app with the better star average is not the one people write more warmly about.

Genetic Code ships an update every 2 months, Biology Knowledge Quiz every 3 weeks. The most recent releases landed on September 7, 2026 and September 22, 2026 respectively.
