Certification Prep Pro

Certification Prep Pro is a native study app for the AWS Cloud Practitioner and Solutions Architect Associate exams. It keeps 1,300+ practice questions, timed exams, quick quizzes, and progress tracking in one focused place on iPhone and Mac.

The problem

AWS exam preparation usually means switching between browser tabs, question banks, notes, and timers. I wanted a study loop that made it easy to answer a useful set of questions, review weak areas, and return later without rebuilding that context.

What it does

• Two exam tracks: AWS Cloud Practitioner and Solutions Architect Associate (SAA-C03)
• 1,300+ questions: more than 600 Cloud Practitioner questions and 700+ SAA-C03 questions
• Two session lengths: 65-question practice exams or 20-question quick quizzes
• Timed practice: exam-style timers and a clear 75% pass indicator
• Useful review: performance broken down by domain and topic
• Native on both platforms: study on iPhone and continue on Mac

The build

The app uses Swift with native SwiftUI and AppKit interfaces for iOS 17.5+ and macOS 14.5+. Sharing the study model across platforms keeps progress and exam behavior consistent, while platform-specific UI preserves the conventions people expect on each device.

Result

Certification Prep Pro is available on the App Store as a distraction-free alternative to browser-based question banks. The product stays deliberately narrow: open it, practice, see where you are weak, and get back to studying.
