Know what your
medications are doing.

Dose estimates each medication's level in your body through the day, from when you took it and a few details about you, and sets it beside your sleep, workouts and how you feel.

Every dose has its own shape.

It builds as your body takes it in, peaks, then fades at the pace of its half-life. Dose works that out from when you took it and a few details about you, using standard pharmacokinetic models.

Put your medications side by side and you can see what is active now, what is fading and what comes next.

Day clock concept: a 24-hour dial with each medication as a shape, sleep and workout bands, and a readout for 14:10

Your day, around the clock.

The day clock draws every medication as a shape around 24 hours, with sleep from Withings and workouts from Hevy on the outside. Doses fill in once taken.

Scrub to any time and see each medication's estimated level, whether it is rising or falling, and when the next dose is due.

Estimates, checked against your labs.

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.

Over time the expected range narrows to fit you. Estimates are always labelled as estimates; measured values always show where they came from.

Expected versus measured concept: an estimated range narrowing over months, with lab results as dots
Mood and energy concept: medication levels across a day with self-reported energy and mood underneath

How you feel, beside the numbers.

Note your mood, energy, symptoms or anything else you track, and see it laid under the day. Weight, body composition, sleep and workouts come in from the services you already use.

Kynytyx shows them side by side. It does not claim one causes the other.

See every integration

See when medications overlap.

Each medication's active hours as a band across the day. When your record has an interaction on file, the hours both are active are highlighted, with where that information came from.

Overlaps concept: bands showing when each medication is active, with an interaction on file highlighted
Widgets and notifications concept: home-screen widgets with a mini day clock and next dose, and lock-screen reminders

Reminders that find you.

On your phone, or by SMS, Telegram, Signal, Pushover or iMessage, and in the calendar you already use. Medication names stay off the lock screen until you turn them on.

Yours to keep, yours to share.
