Questions & Answers

As answered by people managing PMMastery.app and Diffee.

What makes your product unique?

PMMastery.app's answer

PM Mastery is the PMP exam simulator built for the 2026 exam. Mock exams and default practice serve situational questions, the style the 2026 exam uses, and every question explains why the wrong options are wrong. An AI coach on every question lets you ask follow-ups when an explanation doesn’t click. A readiness score by domain (People, Process, Business Environment) shows where you stand, so you know if you’re ready before exam day.

Why should a person choose your product over its competitors?

PMMastery.app's answer

It’s built around the 2026 exam, not adapted from an older one. You get 4,000+ questions, including 200 in 40 case studies, and full 180-question mock exams on paid plans to build the stamina the real test demands. You can start free with 100 questions, and the Exam Prep Pass is a one-time payment for 90 days with no subscription. Every first purchase carries a 7-day money-back guarantee. One thing to know: PM Mastery is a practice platform and doesn’t provide the 35 contact hours PMI requires to apply.

How would you describe the primary audience of your product?

PMMastery.app's answer

Working project managers preparing for the PMP exam, usually studying around a full-time job. Most have already finished their 35 contact hours and want realistic practice to find out whether they’re ready to book or sit the exam.

What's the story behind your product?

PMMastery.app's answer

I’m Ben, a self-taught developer in New Orleans, and I build PM Mastery on my own alongside a full-time job. When PMI changed the PMP exam for 2026, I wanted a simulator built for the new format from the start, so I built one.

Which are the primary technologies used for building your product?

PMMastery.app's answer

Python and Flask on the backend, PostgreSQL for data, JavaScript in the browser, Stripe for payments, and Anthropic’s Claude API powering the AI coach.
