# ABA Wizard vs BCBA Gauge

The clearest difference is price: BCBA Gauge at Free against ABA Wizard's $14.99. BCBA Gauge also leads on review sentiment (100% vs 70%). ABA Wizard's advantage is rating (4.8 vs 3.3) and in-app purchases (none vs 2). On update cadence, device support and iOS requirement there is nothing between them.

BCBA Gauge is free to download; ABA Wizard costs $14.99 up front. BCBA Gauge sells 2 in-app purchases, starting at $1.99 per month. ABA Wizard asks for nothing beyond the download.

ABA Wizard holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: ABA Wizard has 3.9K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 70% of ABA Wizard'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 Wizard ships an update every 3 months, BCBA Gauge every 5 months. Both last shipped on October 22, 2026.
