Verdict

The call

The clearest difference is rating: Relentless Trainer at 4.9 against Chalk Performance Training's 3.8. Relentless Trainer also leads on update cadence (every 3 days vs every 5 months). Chalk Performance Training's advantage is in-app purchases (none vs 9) and ratings volume (166 vs 15). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Relentless Trainer holds the better App Store score, 4.9 against 3.8. That said, the two scores are not equally well evidenced: Chalk Performance Training has 166 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 60% of Relentless Trainer's written reviews are positive against 65% of Chalk Performance Training's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Relentless Trainer ships an update every 3 days, Chalk Performance Training every 5 months. Both last shipped on November 3, 2026.
