# Physique Lab vs Coach OS

The clearest difference is in-app purchases: Physique Lab at none against Coach OS's 6. Physique Lab also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.7). Coach OS's advantage is update cadence (fortnightly vs every 2 months) and ratings volume (89 vs 10). On price, ads and device support there is nothing between them.

Both are free to download. Coach OS sells 6 in-app purchases, starting at $19.99 per month. Physique Lab asks for nothing beyond the download.

Physique Lab holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Coach OS has 89 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 100% of Physique Lab's written reviews are positive against 67% of Coach OS's.

Physique Lab ships an update every 2 months, Coach OS fortnightly. The most recent releases landed on November 12, 2026 and November 8, 2026 respectively.
