Verdict

The call

The clearest difference is rating: Butt Workout Program at 3.8 against Pregnancy App's 1.0. Butt Workout Program also leads on ratings volume (6 vs 1) and iOS requirement (15.6 vs 17.0). Pregnancy App's advantage is ads (none vs shown) and update cadence (every 2 months vs every 12 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Pregnancy App sells 4 one-off in-app purchases and Butt Workout Program sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Butt Workout Program holds the better App Store score, 3.8 against 1.0. That said, the two scores are not equally well evidenced: Butt Workout Program has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 24% of Pregnancy App's written reviews are positive against 0% of Butt Workout Program's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pregnancy App ships an update every 2 months, Butt Workout Program every 12 months. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
