# WHOOP vs NockOut

The clearest difference is review sentiment: NockOut at 100% against WHOOP's 41%. NockOut also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). WHOOP's advantage is ratings volume (87K vs 6) and chart position (#67 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

NockOut holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: WHOOP has 87K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 41% of WHOOP's written reviews are positive against 100% of NockOut's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
