# Posture Chart vs Slouch

The clearest difference is update cadence: Slouch at every 5 days against Posture Chart's every 3 weeks. Slouch also leads on ratings volume (24 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Posture Chart sells 2 in-app purchases, starting at $9.99 per month and Slouch sells 7 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Posture Chart against 5.0 for Slouch. That said, the two scores are not equally well evidenced: Slouch has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 100% of Posture Chart's written reviews are positive against 92% of Slouch's.

Posture Chart ships an update every 3 weeks, Slouch every 5 days. The most recent releases landed on September 28, 2026 and October 7, 2026 respectively.
