# Grade 12 vs E

The clearest difference is rating: Grade 12 at 4.8 against E's 3.9. Grade 12 also leads on iOS requirement (13.0 vs 15.0). E's advantage is ads (none vs shown) and update cadence (monthly vs every 9 months). On price, 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.

Grade 12 holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: E has 30 ratings behind it against 5, so its average is the more settled of the two.

Grade 12 ships an update every 9 months, E monthly. The most recent releases landed on June 10, 2026 and September 23, 2026 respectively.
