NOOP Wiki

Your strap. Your data. Your machine. Local-first, no cloud.

NOOP is an independent, source-available, fully-offline companion app for WHOOP straps (4.0 and 5.0/MG), on macOS and Android. It pairs directly with the strap over Bluetooth, keeps everything on your own device, and recomputes recovery, strain, HRV and sleep locally — no account, no cloud, no subscription.

⚠️ NOOP is an independent, unofficial project — not affiliated with, endorsed by, or sponsored by WHOOP, Inc. "WHOOP" is a trademark of WHOOP, Inc., used nominatively only to identify the hardware NOOP works with. It works only with a device you own, and it is not a medical device. See Privacy and Security and the disclaimer below.
