# Khmer Chemistry vs E

The clearest difference is rating: Khmer Chemistry at 4.8 against E's 3.9. Khmer Chemistry also leads on 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 Chemistry holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: E has 31 ratings behind it against 5, so its average is the more settled of the two.

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