How it thinks
Everything about you, in one model.
Most tools look at one number at a time. Halftime holds your entire physiology in view at once — so a shift in one system informs the response in another.

60+ biomarkers across seven systems, retested every 90 days.
Wearables
Coming soonSleep, activity and recovery from your device — on the roadmap.
Symptoms & goals
How you feel and what you’re working toward, in your words.
Response over time
How your body answers each adjustment, learned test over test.

The closed loop
It never stops learning about you.
Every retest and check-in feeds back in. Your protocol isn’t set once — it’s refined as your biology responds.
01
Measure
A full panel establishes your baseline across every system.
02
Map
The engine builds a protocol around what your biology actually needs.
03
Monitor
Check-ins and how you feel track your response between tests. Wearable sync coming soon.
04
Adjust
Your plan is refined — and the loop begins again, sharper.
Intelligence, supervised
The AI does the analysis. A physician makes the call.
Every protocol and adjustment is reviewed and approved by a licensed clinician before it reaches you. The intelligence scales the attention — the judgment stays human.
