What it’s not

What Sentinel is not

Sentinel should never sound like a disease detector or a device making medical promises.

Not a medical device
Not a medical device
Not medical efficacy language
Not a reason to weaken wellness disclaimers

Why it matters

What Sentinel is for

Sentinel is there for nights when support during sleep matters more than another summary in the morning.

What it does

Sentinel connects overnight support to the rest of Aftercurrent through Apple Watch monitoring and graded haptics.

How it is described

The site keeps the language in sleep support, disturbance monitoring, and wellness terms.

What it avoids

It never claims medical authority or promises clinical care.
