Leaflet helps you learn Swift/SwiftUI and Data Structure/Algorithms better. Leaflet has four main functions: 【1】Algorithm Animation Visualization Through exquisite and intuitive animation demos, abstract algorithms and data structures are made visual — every step of execution is clearly visible. This is the core highlight of Leaflet. - Animation Demos: Carefully selected classic algorithms (sorting, searching, graph algorithms, dynamic programming, recursion, etc.) built with SwiftUI + Combine for smooth animations that make algorithm execution crystal clear. - Interactive Playback: Support play, pause, step forward / step backward, and adjustable playback speed — control your learning pace freely. - Data Structure Visualization: Arrays, linked lists, stacks, queues, trees, graphs and other data structures are presented graphically; insert, delete, and traverse operations are intuitive at a glance. - Synchronized Code View: Animation demos are displayed alongside the corresponding Swift source code, letting you learn code while watching the animation — more efficient learning. - Complexity Analysis: Visually shows the time / space complexity trends of algorithms, helping you build performance-analysis thinking. Learning algorithms is no longer dry code reading, but a vivid visual experience — every algorithm becomes something you can "see and touch". 【2】Swift Tutorial - Swift one-hour micro class, quickly master the core knowledge points of Swift grammar - Swift5 complete tutorial covering all language features from beginner to advanced - Swift Code Style Guide for writing more standardized code - Swift design pattern practice 【3】Swift + SwiftUI + Combine SwiftUI's declarative UI paired with Combine's functional reactive framework — simple to learn, high-performance, and reliable, enabling developers to quickly build elegant applications. 【4】Algorithm Solutions Curated representative algorithm problems implemented in Swift, covering data structures and algorithm analysis to help you master algorithm complexity and performance analysis. Part of the application is based on the open source protocol from the following open source libraries, Gratitude: https://github.com/raywenderlich/swift-algorithm-club , Algorithms and data structures in Swift, with explanations! https://github.com/andyRon/swift-algorithm-club-cn, swift-algorithm-club's translation. Learn algorithms and data structures using Swift.

Verdict
The clearest difference is update cadence: Leaflet for Swift&Algorithm at every 6 days against luai5.2.1's every 3 months. Leaflet for Swift&Algorithm also leads on ratings volume (297 vs 7). luai5.2.1's advantage is monetization model (free vs free with in-app purchases) and review sentiment (91% vs 71%). On price, rating, ads and in-app purchases 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. luai5.2.1 sells 7 one-off in-app purchases and Leaflet for Swift&Algorithm sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Leaflet for Swift&Algorithm holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Leaflet for Swift&Algorithm has 297 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 91% of luai5.2.1's written reviews are positive against 71% of Leaflet for Swift&Algorithm's, so the app with the better star average is not the one people write more warmly about.
luai5.2.1 ships an update every 3 months, Leaflet for Swift&Algorithm every 6 days. Both last shipped on September 21, 2026.
