What the Coach does

Intelligence, built on your data

Nine ways the app works for you between check-ins — all private, all on your device.

📅

Today

Your Coach dashboard: today's targets, what changed since yesterday, and an Explore hub into everything below.

💬

Ask the Coach

Ask a question, get an answer grounded in your own numbers — a private, on-device Q&A engine, not a generic chatbot.

🎓

Coaching

Three evidence-based coaches — Nutrition, Fitness, and Health — with 178 cited principles, plans, myths, and targets from WHO, ACSM, the Dietary Guidelines, and more.

📋

My Plan

Your meal and exercise week rebuilds itself from what you actually logged, your goals, and your trend — and adjusts when progress stalls.

🧪

Simulate

What-if, weight-trajectory, and meal-timing simulators — see how a change plays out before you make it.

🔋

Readiness

A daily readiness read from your sleep, recovery, and vitals, so you know whether today is a push day or a rest day.

🔗

Insights

Cross-domain patterns across sleep, food, activity, and vitals — the correlations you would never spot by eye.

🎯

Goals & Check-ins

Set the goals that matter to you and check in regularly to keep your plan honest and your Coach current.

📈

Weekly Review

A weekly wrap-up of what moved, what did not, and what to focus on next.

Live demo

Your 10 health KPIs, scored in real time

The app scores ten dimensions of your health from what you log. Move the sliders to see how everyday habits shift the scores — the same ten the Coach watches for you.

–
Overall wellness score

A weighted read across all ten. In the app this is computed from your real logs and trends, not sliders.

Illustrative scoring for the demo. In the app, each KPI is computed from your logged nutrition, activity, sleep, and vitals — with a seven-day trend and specific, ranked recommendations.

Insights you would miss by eye

It connects what happens across your week

Examples of the cross-domain patterns the Coach surfaces from your own history.

Sleep × heart rate

Your resting heart rate ran 4 bpm higher on weeks you slept under 6.5 hours — a signal your recovery was running short.

Steps × sleep

On days you passed 8,000 steps, you fell asleep faster and slept about 40 minutes longer that night.

Late meals × morning glucose

Dinners after 9pm tracked with higher fasting glucose the next morning — worth shifting earlier.

The guidelines behind each target in the KPI demo above. Links open in a new tab.

Healthy diet — at least 400g (about 5 servings) of fruit and vegetables a day, the target behind the Veg & fruit slider (Nutrition Quality, Nutrition Adequacy). WHO
Guidelines on physical activity and sedentary behaviour (2020) — 150 min/week moderate aerobic activity (about 5 sessions) and muscle-strengthening on 2 or more days a week, the targets behind Cardio and Strength sessions. WHO
About Sleep — adults should get 7 or more hours a night; a joint AASM/Sleep Research Society consensus panel sets the healthy range at 7-9 hours, the target behind the Sleep slider. CDC / AASM
Association of Daily Step Count and Step Intensity With Mortality Among US Adults — mortality risk kept falling out to 12,000 steps/day, with 8,000 already capturing most of the benefit over 4,000. 10,000/day is used as the full-credit target for the Steps input in Activity Volume, matching the app's own Activity Volume KPI. JAMA, 2020
Water: How much should you drink every day? — eight 8-ounce glasses a day is the commonly used general benchmark (individual needs vary; NASEM's Dietary Reference Intakes put total daily fluid nearer 9-13 cups depending on sex), the target behind the Water slider. Mayo Clinic
Does physical activity attenuate, or even eliminate, the detrimental association of sitting time with mortality? — sitting 8 or more hours a day was the highest-risk band in this pooled analysis of over 1 million adults, the basis for treating longer Sitting as lower-scoring in Recovery & Sedentary Time. The Lancet, 2016
All About Heart Rate (Pulse) — a normal adult resting heart rate is 60-100 bpm, and well-trained individuals are often lower (40-60 bpm), the basis for scoring Resting heart rate in Vitals & Biofeedback. American Heart Association

This demo is a simplified illustration. In the app, each KPI is computed from your own logged nutrition, activity, sleep, and vitals against these and other cited targets, personalized to your profile. Get the app →
