Speederview vs AlgoLens

Prepare for coding interviews faster with real solutions, real structure, and real understanding. Speederview is a coding interview practice app where you solve problems by rebuilding valid solutions from code blocks instead of typing everything from scratch. It is designed to help you recognize patterns faster, understand how strong solutions are structured, and prepare efficiently under real interview pressure. Every challenge is based on correct, optimal solutions, so you are learning the version that actually matters. Instead of memorizing random snippets, you train on the essential flow of proven algorithms across languages like Swift, Kotlin (more to come) Why Speederview stands out - Practice by reconstructing real working solutions - Learn from optimal solutions, not toy implementations - Build intuition for arrays, graphs, trees, dynamic programming, heaps, and more - Strengthen algorithm structure, syntax recognition, and interview speed - Track your progress as you solve more challenges Works offline The core solving experience works offline. Because challenges are backed by structured solution graphs, you can keep practicing even without a connection. That makes Speederview ideal for focused study sessions, commuting, travel, or efficient interview preparation whenever you have a few minutes. Built for efficient interview preparation Speederview is especially effective when you want to improve quickly. It removes the blank-page friction of traditional coding practice and helps you focus on the parts that matter most: - recognizing patterns - understanding dependencies - internalizing optimal solution flow - getting interview-ready faster Train smarter. Review faster. Understand deeper. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

AlgoLens teaches coding patterns the way they actually click — through real-world stories, interactive visualizers, and guided practice. Instead of memorizing abstract algorithms, see why and where each pattern is used in real software systems: • Fraud detection → Sliding Window • Duplicate payments → HashMap • Undo / Redo → Stack • Recently Played → Arrays • Friends of friends → Graph BFS • Calendar conflicts → Merge Intervals Eight pattern paths so far: • Arrays • HashMaps • Two Pointers • Sliding Window • Stack & Queue • Trees • Graph Basics • Merge Intervals Each lesson includes: • A real-world story that anchors the pattern in memory • An interactive visualizer — step through, play, watch the work happen • Guided practice problems with explanations • An interview-ready breakdown with time/space complexity, vs. brute force, and a Swift code sample in a syntax-highlighted editor Practice mode adds three coding game types: • Fill in the blanks — tap a token, drop it into the right slot • Sort the code — shuffled lines, tap two to swap them into order • Find the bug — read the function, tap the line that doesn't match the title Stack streaks, earn XP, and filter puzzles by the companies that ask similar questions in interviews — Google, Meta, Apple, Amazon, Microsoft. Built for mobile-first learning. iPhone-sized, dark code editor styling, short focused lessons designed for the in-between moments. Understand patterns visually. Remember them through stories. Apply them like real engineers.
