Zero-input meal detection

Your body already knows.

Meal Tracker detects every meal from biosignals alone — skin temperature, heart rhythm, wrist motion. No logging. No photos. No input.

01 — The problem

Food logging dies by day nine.

Every diet app asks you to do the work — photograph, search, weigh, confirm. Most people stop within two weeks, and the data stops with them. The failure was never willpower. It was the input.

Eating is a physiological event.

01

Skin temperature

Digestion raises wrist temperature by 0.2–0.4°C within minutes of a meal. We watch for the curve.

02

Heart rhythm

Heart rate rises and variability dips as blood shifts to the gut — a signature no tap can fake.

03

Wrist motion

Hand-to-mouth cadence is as distinct as a gait. Micro-motion confirms the moment.

04

Location context

GPS maps where meals happen, drawing the journey between them — synced with social activity, no check-in.

Four signals. One unambiguous answer — on-device, in real time.

A day, read by your body.

Meal Tracker learns your eating rhythm — when meals tend to happen, and how long they tend to last. A pattern, not a ledger. Raw biosignals never leave the wrist.

Early Morning Midday Evening Late

One signal, four tiers of use.

The same zero-input meal detection serves four markets, graded by analytical accuracy and medical applicability. Lower tiers need only trends; higher tiers extend to clinical-grade data.

Basic monitoring Medical-grade data
01 Welfare · Facility care
Basic — trend watch

Elder nutrition monitoring

Publicly funded care facilities monitor meal regularity and nutrition of residents under care — with zero input.

02 B2C · Lifestyle
Standard — behavior patterns

Social & coaching apps

A consumer app layer for diet socials, dining-out communities, fitness and 1:1 coaching services, and influencer challenges.

03 B2B2C · Clinics
Advanced — adherence tracking

Post-procedure care at obesity clinics

Obesity clinics offer a paid, Meal Tracker-based meal-management service to patients after procedures.

04 B2B · Medical
Medical — clinical grade

Metabolic medical data

Screening centers and medical institutions use it as medical data for complex metabolic care — clinical trials, insurance, and other specialist B2B domains.

Eat. That's the whole workflow.

Meal Tracker runs silently on the wearable you already own.

Stop logging.
Start knowing.
