ReceptionRating · Positive reviews · Number of ratings

20 Pull Ups Trainer Challenge holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: 20 Pull Ups Trainer Challenge has 890 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 48% of 20 Pull Ups Trainer Challenge's written reviews are positive against 80% of RepUp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

20 Pull Ups Trainer Challenge ships an update every 2 months, RepUp every 3 weeks. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
