Verdict

The call

The clearest difference is rating: Official CDFM Practice Test at 4.5 against PMI Study Hall's 3.3. Official CDFM Practice Test also leads on ratings volume (168 vs 12) and iOS requirement (15.0 vs 17.6). PMI Study Hall's advantage is in-app purchases (none vs 3) and review sentiment (25% vs 0%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Official CDFM Practice Test holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Official CDFM Practice Test has 168 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 25% of PMI Study Hall's written reviews are positive against 0% of Official CDFM Practice Test's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PMI Study Hall ships an update every 2 months, Official CDFM Practice Test every 5 months. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
