Before you submit
- I attached my exported NOOP .zip (not a screenshot of the Live screen). If my bug is a clearly reproducible UI issue I described exactly how to see it instead.
- I attached or pasted a strap log above — or my bug is a clearly reproducible UI issue that doesn't need one (e.g. a typo, a button that does nothing) and I've described exactly how to see it.
- I checked the Troubleshooting guide — especially "history syncs but no data" (most often the strap isn't banking history to flash; charge it to 100% and reconnect).
- I checked the FAQ and — if I'm on a WHOOP 5.0 / MG — the 5.0/MG status page, and this isn't an already-known limit (e.g. SpO₂, or recovery/sleep on the 5/MG).
- I've left out anything personal (strap serial, account email, raw export).

Thanks for the log. Sleep detection is actually working — the log shows it recognized sleep for July 15 (339 min), July 16 (448 min), and July 17 (127 min), with HRV and resting HR computed for those nights. The issue is that July 18, 20, and 21 have no sleep data at all (
totalSleepMin=nil, matched=0), and July 19 has no entry at all.The backfill completed successfully but was very small (only 4 chunks), which suggests the strap didn't have much new data to hand over. This usually means the strap wasn't recording usable overnight data for those recent nights.
A few things to check:
If you were wearing the strap with charge and not using the WHOOP app, try charging to 100% and reconnecting — sometimes a full charge cycle gets the strap banking history again.

First of all, as you can see, the amount of sleep it tracked was really low ( I slept for more than 8 hours from July 15th-17th, and it detected only 2 or 3). Next, I was wearing the strap from the 18th-21st, as well as today (22nd), and I also had more than 8 hours of sleep, but it detected nothing. I charged it to 100% on July 19th. I will try again today and see. I do not have the Whoop app installed at all. Thank you for your reply.
