K8s Guide

K8s Guide is a complete study companion for the five Kubernetes and Cloud Native certifications: CKA, CKAD, CKS, KCNA, and KCSA. Every lesson, every practice question, every certification track.

WHY IT'S DIFFERENT

Most exam-prep apps are a static pile of flashcards. K8s Guide adapts to you: an adaptive quiz engine weights questions toward whatever you're actually getting wrong, so weak areas resurface more often instead of drilling what you already know. A mastery engine blends quiz accuracy with lesson completion into a single readiness score per certification, so you always know what to study next - not just what you've already covered.

WHAT'S INCLUDED

• All 5 certifications, fully built out - CKA, CKAD, CKS, KCNA, and KCSA, with 600+ practice questions and 150+ in-depth lessons across 30 exam domains • Adaptive quizzing in Study mode (instant feedback and explanations) or Test mode (full exam simulation, results at the end) • A mastery dashboard per certification: accuracy, lesson coverage, readiness, and weak-domain call-outs • Bookmark any lesson or question for quick review later, synced across your devices • Home Screen widgets showing your streak, active certification progress, and a rotating Kubernetes tidbit • Optional local study reminders, timed to your own schedule • Kubestronaut badge tracking via your public Credly profile (entirely optional) • iCloud sync for progress, quiz history, and bookmarks - tied to your own private iCloud account, not a server we run

BUILT DIFFERENTLY, ON PURPOSE

There's no account to create, no login, and no data collection of any kind - your study data lives in your own iCloud account and nowhere else.

Kubernetes itself is open source and built on the idea that knowledge should be open to everyone. This app is built on the same idea.

Whether you're chasing your first certification or going for the full Kubestronaut set, K8s Guide is built to get you there.
