# FirstWork vs Understanding Behavior BCBA

The clearest difference is update cadence: FirstWork at every 8 days against Understanding Behavior BCBA's every 2 months. Understanding Behavior BCBA's advantage is rating (5.0 vs 4.7) and ratings volume (88 vs 14). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. FirstWork sells 1 in-app purchase, starting at $12.99 per month and Understanding Behavior BCBA sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
