The first 7 nights after you install Shift are spent building your personal baseline. Until then we use population estimates and show a wider confidence interval. If you've been wearing your Apple Watch overnight for more than 7 days and the estimate still looks off, check that "Sleeping Wrist Temperature" is recording in the Health app (Browse → Body Measurements). On a sterile review device with no wrist temperature history, Shift falls back to a synthetic preview so the UI still renders — that's expected.
Wrist temperature is only recorded on Apple Watch Series 8 or newer, when worn during sleep. The Sleep Focus / Sleep Schedule must be configured in iOS Health for the watch to know you're asleep. Take ~5 nights to start producing readings.
