# Delta vs Learn & Code

The clearest difference is rating: Learn & Code at 4.6 against Delta's 3.1. Learn & Code also leads on update cadence (every 4 days vs monthly) and ratings volume (125 vs 7). Delta's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Delta sells 3 one-off in-app purchases and Learn & Code sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Learn & Code holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: Learn & Code has 125 ratings behind it against 7, so its average is the more settled of the two. Written reviews split almost evenly too, at 67% and 67% positive.

Delta ships an update monthly, Learn & Code every 4 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
