Rhythm

See how your body changed the night.

Rhythm brings Body Readiness, sleep timing, HRV, resting heart rate, trends, and Sentinel into one place so you can tell whether a rough morning came more from the dream, the body, or both.

Body Readiness

Recovery matters more when it has a clear read.

A score alone only tells you so much. Body Readiness is more useful when it sits beside the dream, the night, and what has been recurring lately.

In the current build, Aftercurrent calculates it from sleep duration, HRV, and resting heart rate.

Trends

One weird night is noise. Trends tell you when something changed.

Trends help you tell the difference between a strange night and a real shift.

That matters when you are trying to read a dream honestly or understand a rough stretch.

One rough night can mislead you.
Trends show when something is actually moving.
The app keeps body context connected to Journal, Today, and Insights.

Sentinel

Sentinel adds Apple Watch support for rough nights.

It looks for nighttime disturbance patterns using heart rate, HRV, and motion, then saves the event for morning review when the read is clear enough.

When those signals line up, it can respond with gentle haptics during the night and keep that event inside Aftercurrent for the morning.

Sentinel is a wellness feature, not a medical device.

A score means more when it sits next to the dream.

That is why Rhythm belongs inside Aftercurrent instead of living beside it.
