# pliability vs Chalk Performance Training

The clearest difference is rating: pliability at 4.8 against Chalk Performance Training's 3.8. pliability also leads on update cadence (every 5 days vs every 5 months) and ratings volume (10K vs 164). Chalk Performance Training's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

pliability holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: pliability has 10K ratings behind it against 164, so its average is the more settled of the two. Written reviews complicate that: 41% of pliability'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.

pliability ships an update every 5 days, Chalk Performance Training every 5 months. The most recent releases landed on October 16, 2026 and October 7, 2026 respectively.
