Verdict

The call

The clearest difference is review sentiment: RM at 100% against My 1 Rep Max's 57%. RM also leads on in-app purchases (none vs 1) and device support (3 vs 1). My 1 Rep Max's advantage is rating (4.4 vs 2.0) and ratings volume (119 vs 1). On price and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

My 1 Rep Max holds the better App Store score, 4.4 against 2.0. That said, the two scores are not equally well evidenced: My 1 Rep Max has 119 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 57% of My 1 Rep Max's written reviews are positive against 100% of RM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

My 1 Rep Max ships an update every 11 days, RM monthly. Both last shipped on November 2, 2026.
