# 320 Guide vs E

The clearest difference is rating: E at 5.0 against 320 Guide's 4.6. E also leads on update cadence (weekly vs monthly) and iOS requirement (12.0 vs 14.0.0). 320 Guide's advantage is ratings volume (44 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 320 Guide sells 8 in-app purchases, starting at $9.99 per month and E sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

E holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: 320 Guide has 44 ratings behind it against 1, so its average is the more settled of the two.

320 Guide ships an update monthly, E weekly. Both last shipped on November 3, 2026.
