Gapfyre SWE — Coding Quiz

Software Engineering Quiz

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Sharpen your software engineering skills with quick quizzes and code questions across dozens of topics. Easily dig deeper with your preferred AI assistant. Dig into the software engineering concepts that interviews and day-to-day work rely on. GapfyreSWE is a training app for developers: over 3,500 questions across 70+ categories, spanning design patterns, SOLID principles, data structures, concurrency, system design, databases, cloud and the rest of the working stack — written to be answered in a spare five minutes rather than a study session. Dig deeper with AI Every question you review carries a "Dig deeper" link. It opens your chosen assistant — Claude, ChatGPT, Copilot, Gemini or Grok — with the question, your answer and the explanation already written out. You ask the follow-up; you do not retype the context. Four kinds of question • Multiple choice — the fundamentals, and why the other three answers are wrong. • Fill the missing line — a snippet with a hole in it, which you cannot bluff. • Order the lines — reassemble a function from shuffled lines. • Spot the bug — real code with one thing wrong in it. Find it.
