About

Speederview

Features
Read full description

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/
