About

Stop drowning in health data.

Charts. Scores. Endless metrics.
Most health apps give you more numbers — not more understanding.

Dayline AI analyzes up to 120 days of your health data and distills it into one clear, human sentence.

Not a dashboard.
Not a report.
One insight you can actually use.

Yesterday, explained by everything that came before it.

Our Mission

Turn 120 days of complex health data into one simple, actionable sentence.

Clarity over complexity.
Insight over information.
Understanding over overwhelm.

How It Works

Every day, Dayline AI reviews patterns across your sleep, activity, recovery, calendar and trends over time.

It connects the dots.
Finds the signals.
Filters the noise.

Then it delivers your Dayline — a single sentence that captures what matters most right now.

And when you want to go deeper, you can.

Ask questions.
Explore patterns.
Have a conversation with your health data.

Understanding, on demand.

With Pro, you get a 120 day context window for deeper patterns and predictions. Readiness is a daily score for today — when to push or ease off. Adaptation is a weekly smoothed score with a month-level view, so you can see if a new routine is sticking. And Bio Age: your body's pace of ageing in plain numbers, so you can see whether you're gaining years or buying them back.
