120 hand-written code puzzles, concurrency, ARC, Code and algorithms. Answer today's question from the widget — no account, no tracking, works offline. Codestion puts one Swift puzzle on your Home Screen every day. ONE PUZZLE A DAY A single multiple-choice question appears on your Home Screen each morning. Tap an answer right there on the widget — the app never has to open. 120 PUZZLES, SEVEN AREAS Swift language, concurrency, memory and ARC, SwiftUI, Foundation, iOS platform, and algorithms. Every question is hand-written, with the mix of difficulty spread across easy, medium and hard. EVERY ANSWER EXPLAINED Right or wrong, you get the reasoning — and why each of the other options fails. The point is the explanation, not the score. KEEP THE STREAK A streak counter, a full archive of past questions, and statistics broken down by category, so you can see which areas you actually know. WHEREVER YOU ALREADY LOOK Small and medium Home Screen widgets, a Lock Screen widget, a Control Center control, Spotlight search, and an optional daily reminder. YOURS ALONE No account. No sign-in. No analytics, no tracking, no ads. Every answer you give stays on your device. The app works entirely offline.
