ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
