Verdict

The call

The clearest difference is review sentiment: SIE Exam Prep at 100% against SIE Exam's 30%. SIE Exam Prep also leads on update cadence (every 2 days vs every 4 months) and monetization model (free vs free with in-app purchases). SIE Exam's advantage is rating (4.5 vs 3.9) and ratings volume (310 vs 8). On price, ads, in-app purchases and device support there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. SIE Exam sells 2 in-app purchases, starting at $24.99 per month and SIE Exam Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

SIE Exam holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: SIE Exam has 310 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 30% of SIE Exam's written reviews are positive against 100% of SIE Exam Prep's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SIE Exam ships an update every 4 months, SIE Exam Prep every 2 days. Both last shipped on October 22, 2026.
