Description by 天从 何 Written by the developer, not by AppBrain. Click to read.
Eight years. One mission: help you master algorithms without distractions.
iCoder is a LeetCode practice app trusted since day one by learners preparing for technical interviews. Version 8.0 marks our 8th anniversary with a complete SwiftUI rebuild: faster, cleaner, and ready for iOS 16 and later. Still 1000+ classic problems, still offline, still no ad popups.
WHY iCODER
- Born for interview prep: company-tagged problems mirror what top firms often ask
- Organized by difficulty, tags, and companies so you can drill weak spots
- Offline-first: the library lives on your device; browse, quiz, and widgets work without Wi-Fi
- Eight years of polish: now with a modern SwiftUI interface and rich widgets
