DATARAKU

An educational visualization app that lets you UNDERSTAND data structures by watching them - not by reading. Abstract concepts like stacks, queues, trees, and hash tables come alive as animations where the structure itself deforms in response to your operations. [ Basics - 4 structures ] - Stack (LIFO) - Feel "last in, first out" through stacking motion - Queue (FIFO) - Watch the entry and exit ends of a queue - Array - Visualize random access and the shifting of elements on insert / delete - Linked List - Nodes connected by arrows, rewired on insert and delete [ Advanced - 4 structures ] - Binary Search Tree - Values drop into place after branching left or right by comparison - Heap - Up-heap and down-heap motion in a complete binary tree - Hash Table - Keys travel through a hash function and land in a bucket - Graph - Nodes and edges showing adjacency [ Features ] - Every operation animates as a continuous deformation (no instant teleporting) - Operation log to review the meaning of each step - Each structure includes complexity notes (access / search / insert / delete), pros and cons, and real-world usage examples - Ads are never shown while an animation is playing - designed to preserve focus - Universal app for iPhone and iPad - Japanese and English (follows OS language) [ Who is this for ] - Students learning programming for the first time - Anyone preparing for IT exams - Engineers who want to re-grasp data structures visually - Curious minds who love watching things move [ Companion to ARURAKU ] The second information-systems title of the Raku Series, sibling to ARURAKU (algorithm visualization). The two apps cross-link, so the heap screen here links to ARURAKU's heap sort, and the graph screen here links to ARURAKU's BFS / DFS. Learn the "motion of computation" and the "structures that carry it" side by side. [ Note on pricing ] This app is completely free with no in-app purchases or subscriptions. To support development and maintenance we display Google AdMob banner and interstitial advertising. Ads are never shown while an animation is playing.

Verdict
The clearest difference is in-app purchases: DATARAKU at none against Algorithmics's 3. Algorithmics's advantage is ads (none vs shown) and iOS requirement (15.1 vs 17.0). On price and device support there is nothing between them.
