# PMP Certification Mastery vs Project Office X

The clearest difference is rating: PMP Certification Mastery at 4.5 against Project Office X's 1.0. PMP Certification Mastery also leads on ratings volume (703 vs 2) and update cadence (every 2 weeks vs monthly). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. PMP Certification Mastery sells 3 in-app purchases, starting at $10.99 per month and Project Office X sells 10 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

PMP Certification Mastery holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: PMP Certification Mastery has 703 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 46% of PMP Certification Mastery's written reviews are positive against 50% of Project Office X's, so the app with the better star average is not the one people write more warmly about.

PMP Certification Mastery ships an update every 2 weeks, Project Office X monthly. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
