Binary Tree Dojo

Watch data structures grow

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Understand data structures instead of memorizing them. Place nodes yourself, rotate the tree straight and see the search get shorter. Fully offline, no account. Binary Tree Dojo makes data structures tangible. No videos, no flashcards: you steer every key left or right yourself and watch the tree grow under your hands. YOUR PATH THROUGH THREE WORLDS From white belt on, one building block at a time: • The first tree: root, leaf, height, insert, search and delete • The three routes: inorder, preorder, postorder and level order • Balance: why sorted input degenerates into a list and how rotations and the balance factor help PLAY INSTEAD OF CRAM Every task is playable in under 90 seconds. First you experience the phenomenon, then it gets a name. Guided rounds to understand, belts from white to green mark your progress. PRIVATE AND OFFLINE No accounts, no servers, no data collection. Everything runs on your device. BINARY TREE DOJO PRO The first two worlds are free. Pro unlocks the further worlds. Subscriptions renew automatically and can be cancelled any time.
