# Khmer Biology vs E

The clearest difference is review sentiment: Khmer Biology at 100% against E's 33%. Khmer Biology also leads on rating (4.5 vs 3.9) and iOS requirement (12.0 vs 15.0). E's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Khmer Biology holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: E has 31 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Khmer Biology's written reviews are positive against 33% of E's.

Khmer Biology ships an update every 5 weeks, E monthly. The most recent releases landed on November 4, 2026 and November 2, 2026 respectively.
