Data Structure Display vs 3D Data Plot
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Data Structure Display
Explore and learn data structures through dynamic debugging and visual observation of changes. This app covers linear structures, trees, graphs, and recursive algorithms like the Tower of Hanoi, offering interactive learning experiences.
- 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.
3D Data Plot

1. Measurement data (CSV file) can be plotted in 3D. • Interprets delimiters other than commas: tab(\t), space(\s) and so on. • Imports the 4th element, which is used as density, concentration and so on. • Imports the value represented with exponential notation "0.0E±0", which is outputted by Excel. • Internal processing in float type, which has a range of ±1E-38 to ±1E+38 with a precision of 6 decimal digits. 2. You can import CSV file in three ways: When completing within one device (iPhone/iPad/Mac). • Create a text file with an application (Notes, Textor, etc.) on the device. • In the application, tap "share button" and then choose “3dDataPlot”. Transfer from Mac to iPhone/iPad • Connect your device (iPhone/iPad) to your Mac via USB cable. • In Finder on your Mac, select the device in the left sidebar and click "File" on the button bar at the right. • Drop a text file into “3dDataPlot” folder. Import from iCloud • Sign in to iCloud.com from browser (Safari, Chrome, etc.) on your Mac. • Select “iCloud Drive”. • Drop a text file into “3dDataPlot” folder.

Verdict
The clearest difference is review sentiment: Data Structure Display at 62% against 3D Data Plot's 0%. Data Structure Display also leads on update cadence (every 5 months vs every 17 months). 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 3D Data Plot sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Data Structure Display ships an update every 5 months, 3D Data Plot every 17 months. The most recent releases landed on September 24, 2026 and September 16, 2026 respectively.
