# Data Structure Display vs Learn & Code

The clearest difference is ads: Data Structure Display at none against Learn & Code's shown. Data Structure Display also leads on ratings volume (676 vs 125) and iOS requirement (13.0 vs 15.0). Learn & Code's advantage is update cadence (every 4 days vs every 5 months). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase 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.

On the App Store both sit at effectively the same score — 4.5 for Data Structure Display against 4.6 for Learn & Code. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 125, so its average is the more settled of the two. Written reviews are what separate them: 62% of Data Structure Display's written reviews are positive against 67% of Learn & Code's.

Data Structure Display ships an update every 5 months, Learn & Code every 4 days. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
