Loop reminders
Never miss a loop step.
Email plus in-app nudges for every step of the quarterly cycle.
Most at-home tests hand you a number and walk away.
Haylo's AI is the part that actually does something with it.
It remembers.
Every quarterly result sits against your own history, not a generic reference range so it catches a slow drift months before a single test would look 'abnormal'.
It explains, in plain language.
Out of 100+ biomarkers, the AI surfaces the few actually worth paying attention to and tells you what they mean in words a normal human understands.
You stay in charge.
Haylo gives you insight and a plan built around your results supplements and lifestyle steps you can start right away. Your body, your call.
It closes the loop.
Next quarter's test tells you whether your plan is working. No guessing, no separate follow-up to schedule yourself.
A test tells you where you are.
Haylo tells you what to do about it — every quarter, without you having to ask.
