Unit Gacha ! vs ARURAKU

◆ Learn Physics Units with a Fun Gacha System Physics Units Gacha lets you practice unit breakdown, unit conversions, and fundamental physical quantities through randomly generated problems. Just tap to get a new question and continue learning at your own pace. ◆ Covers Essential Physics Units Practice and review a wide range of physics units: Mechanics (force, energy, momentum, pressure) Electricity & magnetism (voltage, resistance, charge, field strength) Waves & thermodynamics Derived units SI base units & physical constants Designed for students who want to study physics through units. ◆ Focused Explanations Where Needed Some problems include short explanations that show how units are derived from formulas. ◆ Random Practice Questions are generated randomly, allowing you to encounter various unit patterns and practice repeatedly. ◆ Simple Learning Features In-app scratch paper Learning progress is saved locally, and can be synchronized to the cloud when you sign in. Suitable for both quick review and focused practice sessions. ◆ For High-School Physics & Introductory University Courses A learning app designed to support the study of physics units for exams and fundamental review. ◆ Free to Use (Optional Paid Content) Approximately 70 problems are available for free Additional problem sets are available as optional paid upgrades

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.
