Kodexo Labs designed and specified Decima, an iOS longevity coach that reads a person's Apple Health data, scores their day, and turns it into a small number of things worth doing before bed, spoken in the voice of a coach they picked.
01 · Overview
Decima reads sleep, activity, vitals, and air quality from Apple Health and turns them into one weighted score for the day, a level the person is working up through, and a short list of actions to do next.
The advice is not improvised. Every recommendation is compiled from the client's own health protocols, held as three linked databases of topics, concepts, and science, then spoken back in the voice of the coach persona the user picked.
The level the algorithm assigned from your own biomarkers, and how many days of the week you have held it.
Hours slept against the target, with the awake, REM, light, and deep split shown underneath it.
Each goal carries the specific things to do, written plainly: screens off two hours before bed, room kept at 64 to 68.
02 · The Problem
The client had the science and the protocols. What was missing was a product that could read a person's own numbers and say, plainly, what to do next. Four gaps had to close first.
Apple Health shows sleep, steps, and vitals as separate numbers. Nothing added them up into one score to act on.
The client's own health protocols held the real expertise, but nothing in the app could read them or speak from them.
Without automatic sync, people typed in sleep and vitals by hand, and looked up every meal's calories themselves.
If someone turns off health permissions, the app has nothing to read, and no other way to still be useful.
03 · The Solution
Six screens, six jobs, from the score that opens the app to the data quality behind it.
Instead of a wall of separate readings for sleep, activity, and vitals, Home opens on one weighted score for the day, with the level being worked toward and today's goals sitting right beneath it.
Every action, from a set of push-ups to a bike ride, opens into a stepper or a synced count instead of a form. It's checked against today's target and the streak that keeps someone coming back to it.
The Longevity Keys are the handful of biomarkers proven to move the needle on healthspan. Each one shows where a person stands against their target, with the trend line behind it instead of a single reading.
Sleep opens on the number that matters, hours against target, then breaks the night into awake, REM, light, and deep as clear percentages, followed by the specific wind-down actions worth trying tonight.
Levels turn a long list of biomarkers into a ladder someone can actually climb: completed levels behind them, the current one open, and the locked ones ahead with the exact goals standing in the way.
Before Decima scores a person's day, it scores the data behind it: how much of the last sync was usable, how much fell in range, and the specific habits, like keeping the watch on overnight, that sharpen the next one.
04 · How It Works
No engineering detail needed here. This is the plain-English version of what happens every time someone talks to Decima.
A question, or just a meal photo. Voice and text both work.
Sleep, activity, and vitals from Apple Health, checked against your history.
Your coach's own health protocols, not generic advice.
Spoken back in your coach's voice, with any task added to your calendar.
Built for iPhone first, with Android and web planned next
Cloud infrastructure sized to grow with the user base
Built to HIPAA and GDPR standards, encrypted at every step
05 · Outcomes
What each feature saves someone, measured against the manual routine it replaces.
Sleep, activity, vitals, and daylight arrive from Apple Health instead of being typed in by hand.
A photo or one sentence replaces looking up nutrition tables and doing the arithmetic.
Difficulty adapts to what someone actually completed, with reminders in the calendar they already read.
Chat context becomes search keywords, and a scheduled fetch brings back only what fits the person's goals.
Traits, voice, and behaviour are defined and A/B tested in the Coach Builder, not filed as a ticket.
Built on cloud infrastructure sized to scale with the knowledge base behind it, not around it.
Bring the expertise and the data sources. We will tell you straight what it takes to turn them into a product people open every morning.
