- Dynamic data structure debugging
- Visual observation of data structure changes
- Learn linear structures (arrays, lists, queues, stacks)
- Explore tree structures (binary, AVL, red-black, heap)
- Understand graph structures and algorithms
- Debug recursive algorithms like Tower of Hanoi

A novel data structure learning app, the most significant feature is that you can dynamically debug the data structure in this app, and visually observe the changes in the data structure during the operation. In this app you can learn the following data structures: 1. Linear structures, including arrays, linked lists, queues, stacks. Linear structures are the basis for other advanced data structures, as fine as advanced algorithms. 2. Tree structures, including binary tree, binary search tree, AVL tree, red-black tree, and heap. In this app, you can dynamically debug three traversals of the binary tree (including non-recursive traversal implementations), searching in the tree, balance adjustments in the AVL tree and red-black tree, and heap sorting. Give you the ability of handwritten red-black trees. 3. Graph structure, including the adjacency list storage representation of the graph structure, depth-first search and breadth-first search, finding the Euler path in the graph, topological sorting, maximum connected components, minimum spanning tree problem, and shortest single source Path problem. It also provides dynamic debugging of these classic graph algorithms. 4. The data structure introductory class will talk about the problem of the Tower of Hanoi. The algorithm that solves this problem is often recursive. This app provides dynamic debugging of the Tower of Hanoi problem, so you can no longer be confused about the recursive calls of the Tower of Hanoi.

Verdict
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 (85% vs 62%) and rating (4.7 vs 4.5). Data Structure Display's advantage is ratings volume (678 vs 141) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 — 678 and 141 respectively. Written reviews point the same way: 62% of Data Structure Display's written reviews are positive against 85% of Neural Network's.
Data Structure Display ships an update every 5 months, Neural Network every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
