Verdict

The call

The clearest difference is price: 21 Day Container Workout Fix at Free against Soft Challenge's $1.99. 21 Day Container Workout Fix also leads on update cadence (every 5 days vs fortnightly) and iOS requirement (12.0 vs 16.4). Soft Challenge's advantage is rating (4.8 vs 4.1) and in-app purchases (none vs 2). On review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Soft Challenge holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Soft Challenge has 286 ratings behind it against 43, so its average is the more settled of the two. Written reviews complicate that: 67% of 21 Day Container Workout Fix's written reviews are positive against 64% of Soft Challenge's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

21 Day Container Workout Fix ships an update every 5 days, Soft Challenge fortnightly. The most recent releases landed on October 11, 2026 and October 21, 2026 respectively.
