ARURAKU vs Origami Learn

ARURAKU is an educational visualization app that helps you understand algorithms by watching them move, not by reading about them. Sorting, searching, and recursion come alive in animations that advance one step at a time. [ Algorithms ] Sorting (6) - Bubble sort / Selection sort / Insertion sort - Merge sort / Quick sort / Heap sort Race Mode runs two to four algorithms on the same array side by side, so the difference in complexity is obvious at a glance. Searching (4) - Breadth-first search (BFS) / Depth-first search (DFS) - Dijkstra's algorithm / A* Watch how each pathfinder spreads through a grid maze. Tap to edit walls, or generate a new maze. Recursion - Tower of Hanoi (3 to 8 discs) - Fractals: Koch curve, Sierpinski triangle, recursive tree (adjustable depth) [ Features ] - Colors and motion show what is happening: comparisons in orange, swaps in green - Speed control, pause, and step-by-step execution - Array patterns (random / nearly sorted / reversed / many duplicates) and element count - An explanation for every algorithm: how it works, complexity, strengths, weaknesses, and real-world use - No ads while an animation is playing - iPhone and iPad - Available in more than 70 languages (follows your device language) [ Who it's for ] - Students just starting to learn programming - Anyone preparing for IT certification exams - Engineers who want to sharpen their feel for complexity - Anyone who simply enjoys watching things move [ Pricing ] ARURAKU is free. There are no in-app purchases or subscriptions, and every feature is available from the start. To support development, the app shows ads, for example at the bottom of menu screens. Ads are never shown while an algorithm animation is playing. You can choose whether to allow ads based on your interests (personalized ads) at any time from "Ad settings" on the home screen. The first information-systems title of the Raku Series.

Origami Learn is a folding simulator, not a picture book. Every one of the 959 steps in this app is real geometry. The paper on screen is a simulated sheet with layers and creases, so you can drag a fold half-way and hold it there, turn the sheet over to see which flap moves, and replay the same crease as many times as you like. Nothing here is a photograph or a video. That is why it can unstick you when a diagram in a book cannot. 148 MODELS, 122 FREE FOREVER 116 origami models, 9 modular pieces built from folded units, and 23 kirigami designs you fold and cut. Cranes, boxes, flowers, animals, insects, stars, snowflakes, and the traditional children's furniture set. Each one is a genuine traditional design, with the region it came from and the paper it wants. A COURSE, NOT A CATALOGUE Nine chapters take you from "what is a valley fold" to bird bases, reverse folds, modular units and open-and-pull. Twelve lessons and seven practice sets, each unlocking the models that use what you just learned. Search the whole path, switch to a chapter grid, or ask for just the next thing in each chapter. LEARN TO READ ORIGAMI BOOKS Beside the live paper, every step is also drawn the way an origami book draws it: the standard symbols, dashed valley and dash-dot mountain creases, and fold arrows anchored to the corner that actually travels. Learn these and the rest of origami literature opens up. BRING IT TO LIFE Finish a model and decorate it. Thirty-six vector stickers — eyes, mouths, whiskers, leaves, stars — in any colour, plus freehand drawing. Print it, share it as a picture, or keep it in your gallery. Twenty models can be set moving and saved as a looping GIF: the flapping bird flaps, the frog jumps, the tulip opens. FOLD WITH YOUR HANDS FULL Say "next", "back" or "again". Speech is recognised entirely on your device and no audio ever leaves it. Or let the app read each step aloud while you keep both hands on the paper. IPHONE, IPAD, MAC AND APPLE WATCH One purchase covers all four. On Apple Watch the Digital Crown becomes a fold scrubber: rotate to close the crease, feel a tap when it lands, and the step moves on by itself. Add a complication and the watch face puts you back at the step you left. Progress follows you between wrist, phone, tablet and desk. MAKE IT YOUR PAPER Choose the colour of both sides of the sheet, per model or everywhere, including a colour-blind-safe pair told apart by lightness rather than hue. Print true-size squares and grids from Paper Tools. Design your own snowflake in Snowflake Studio and watch the cuts mirror around the wedge. BUILT TO BE READ Full VoiceOver in the player, Dynamic Type throughout, Reduce Motion that swaps animation for clear before-and-after states, AA contrast, and Kids Mode that hides anything needing scissors. FIVE LANGUAGES, COMPLETELY English, Tiếng Việt, 日本語, Español and 简体中文 — not only the buttons, but every model name, every step instruction, every tip, lesson and glossary entry. Switch language in Settings and the whole app reloads in it. NO ADS. NO TRACKING. NO ACCOUNT. There is nothing to sign up for and nothing to collect. No analytics, no advertising, no third-party SDKs. Your progress and your photographs stay on your device, and the whole library works offline.
