Sample day, for illustration. Each shape is scaled to that medication's own peak.

Know where you are in your day.

Each dose builds, peaks and fades on its own schedule. Dose works that out from when you took it and a few details about your body, using standard pharmacokinetic models. Side by side, they show what is active now and what comes next.

  • Your own data, alongside
    Weight, body composition, sleep and workouts from services you already use, including Withings, BodySpec and Hevy, with more on the way. Kynytyx is not a medical device; it reads from the ones you already use.
  • How you feel, too
    Note your mood, energy or anything else you notice, and see it beside the numbers.
  • Estimates, then lab results
    When a lab panel comes back, from a connected lab partner or added by you, Dose sets the measured level beside the expected one and corrects its estimates from there.

Bring in what you already track.

Kynytyx reads from the services and devices you already use, and lab results as they come in. It is not a medical device itself.

Kynytyx keeps the record. It is not a medical device: it reads data from the devices and services you already use, and does not give medical advice. Decisions about treatment belong with your care team.
