n1lab is not a medical instrument.

It records observations and surfaces patterns. It does not diagnose, treat, or recommend. The readings it gathers are intended to be brought into a conversation with a clinician, not to replace one.

If you are looking for a tool that will tell you what to do, n1lab is not it. If you are looking for a place to keep careful records and watch them over months, you are in the right place.
