# ABA Exam vs BCBA Gauge

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.

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.

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.
