# PostureFlow vs Rehab Science

The clearest difference is review sentiment: Rehab Science at 100% against PostureFlow's 70%. Rehab Science also leads on rating (5.0 vs 4.7). PostureFlow's advantage is ratings volume (26 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PostureFlow sells 4 in-app purchases, starting at $12.99 per month and Rehab Science sells 2 in-app purchases, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.

Rehab Science holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PostureFlow has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 70% of PostureFlow's written reviews are positive against 100% of Rehab Science's.

PostureFlow ships an update every 6 weeks, Rehab Science monthly. The most recent releases landed on October 24, 2026 and October 11, 2026 respectively.
