# Data Structure Display vs Neural Network

The clearest difference is update cadence: Neural Network at every 3 weeks against Data Structure Display's every 5 months. Neural Network also leads on review sentiment (81% vs 62%) and rating (4.7 vs 4.5). Data Structure Display's advantage is ratings volume (676 vs 140) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase and Neural Network sells 3 in-app purchases, starting at $12.99 per 6 months. Whichever you choose, the download price is not the number that matters.

Neural Network holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 676 and 140 respectively. Written reviews point the same way: 62% of Data Structure Display's written reviews are positive against 81% of Neural Network's.

Data Structure Display ships an update every 5 months, Neural Network every 3 weeks. Both last shipped on September 24, 2026.
