# Relentless Trainer vs Chalk Performance Training

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.

Both are free to download. Relentless Trainer sells 9 in-app purchases, starting at $9.99 per month. Chalk Performance Training asks for nothing beyond the download.

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.

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