Verdict

The call

The clearest difference is review sentiment: BCBA Gauge at 100% against ABA Exam's 40%. ABA Exam's advantage is rating (4.8 vs 3.3) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. ABA Exam sells 2 in-app purchases, starting at $24.99 per month and BCBA Gauge sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

ABA Exam holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: ABA Exam has 317 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 40% of ABA Exam's written reviews are positive against 100% of BCBA Gauge's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ABA Exam ships an update every 3 months, BCBA Gauge every 5 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
