CHI is not an emergency or clinical-risk score. For a possible emergency in India, call 112 or go to the nearest emergency department. Do not wait for CHI to update or for an app response.

Understand your changing health patterns with the Nily Composite Health Index

Health information is usually fragmented: how you feel today, what you tracked last week, a wearable signal, a habit, an assessment or a report. Each reading is a snapshot; the pattern lives across weeks.

The Nily Composite Health Index—CHI—organizes selected, consented health and wellbeing signals into a changing personal view. It helps you see what is contributing, how much data supports the view and what may deserve reflection or an appropriate next step.

Begin Building My CHI Start a Daily Health Check-In

You choose which supported sources contribute—nothing starts without your explicit consent, and you can review the method and disconnect a source at any time.

CHI is designed for longitudinal tracking and reflection. It is not a diagnosis, prognosis, emergency score, medical clearance or guarantee of future health.

What is the Nily CHI health score?

The Nily CHI (Composite Health Index) is a personal health score that organizes your consented check-ins, trackers, assessments and connected signals into one changing view over time. It shows what is contributing, how much data supports it and what may deserve attention next. CHI is a tracking view, not a diagnosis or a one-off health score calculator.

CHI is built as the centerpiece of a personal health dashboard India can use day to day—not a universal global scoring template. Some people search for this idea as a wellness score or a health and wellness score; on Nily, that is the CHI described on this page, kept longitudinal and versioned rather than a single static number.

Ubersuggest India/en data reviewed 16 July 2026: health score app receives roughly 260 monthly searches; results are commonly polluted by financial-health intent, so this page always keeps the personal-health context attached.

What CHI brings together

Each supported source keeps its own meaning and limits. CHI never fills a skipped question with an assumed value, and more trackers do not automatically improve score quality.

Approved self-reported check-ins

Selected daily responses can contribute when the current CHI method includes them and the user has consented. Skipped questions remain missing; Nily must not fill them with assumed values.

Selected health trackers

Relevant trackers may contribute only when enabled, sufficiently current and supported by the approved algorithm version. More trackers do not automatically improve score quality.

Assessments and program context

An assessment or program may add defined context without converting a screening result into a diagnosis. Each input must retain its original meaning and limitations.

Connected device or wearable signals

Supported passive signals may contribute only when the source, permissions, time range, data quality and algorithm treatment are clear. A device connection does not guarantee accurate or complete data.

User context and data history

CHI should distinguish personal longitudinal change from a universal population ranking. The approved method—not marketing copy—determines how context and history are handled.

Missingness, freshness and confidence

The score view must show when information is missing, old, inconsistent or insufficient. Missing data is not automatically poor health, and recent data is not automatically accurate data.

How the Nily CHI method works

Step 1

Accept only consented, supported inputs

Use defined sources from the versioned CHI input registry. Do not add a new tracker, wearable or assessment to the score merely because the data exists.

Step 2

Check quality, freshness and completeness

Identify missing, stale, duplicate, implausible or unsupported information according to approved rules. Preserve source and timestamp provenance.

Step 3

Calculate approved domain contributions

Apply the current CHI algorithm specification to supported domains. Do not disclose fabricated weights or let the public page become a second source of scoring truth.

Step 4

Create the composite longitudinal view

Combine approved contributions under the current algorithm version. The composite must not erase important domain-level change or safety information.

Step 5

Assign a data-maturity state

Show whether the view is Building, Early, Moderate or Stable based on approved data sufficiency and maturity rules. These labels describe the evidence supporting the personal pattern—not whether the person is healthy.

Step 6

Explain what changed

Show contributing domains, input dates, missing-data effects and the algorithm version in plain language. Never present a score change without an accessible explanation.

CHI data-maturity states

State What it communicates What it must not imply
Building The CHI is still gathering enough supported information to establish an initial view Poor health, low engagement or a failed score
Early An initial personal pattern is visible but can change substantially as more data arrives Clinical certainty or reliable prediction
Moderate Repeated supported inputs provide more longitudinal context Diagnosis, medical stability or complete data
Stable The available personal data history is comparatively established under the current method "Healthy," safe, permanent or no need for care

The approved CHI algorithm specification defines state transitions. Numeric thresholds are never published or changed through marketing content.

What CHI is—and what it is not

CHI is designed to CHI is not designed to
Organize selected signals into a changing personal view Diagnose a disease or mental-health condition
Show contribution, trend, data maturity and missing information Predict an emergency, hospitalization or lifespan
Support reflection and better-prepared questions Replace examination, laboratory interpretation or clinical judgment
Connect relevant Nily trackers and programs Rank people publicly or determine personal worth
Help notice change over time Provide insurance, employment or credit decisions
Point to appropriate care navigation Delay urgent care because a score looks reassuring

Where CHI fits in the Nily journey

Use Personalized Health Tracking to review the underlying selected signals rather than relying on the composite alone. See How Nily Works to understand the path from assessment and daily check-ins to patterns and next steps.

When you want structured ongoing support, compare Health Programs. When you need a test, consultation or another defined pathway, review Health Services. If a change, symptom or result needs individual medical judgment, consider an Online Doctor Consultation or appropriate in-person care.

Why your CHI may change

CHI may change because new supported information was added, an input became stale, a tracker was corrected, an algorithm version changed or a contributing domain shifted. The product must identify which explanation applies. Do not attribute a change to one habit, medicine or event unless the evidence supports that conclusion—correlation does not prove cause.

Comparison period

The comparison period and last updated time.

Contributing domains

The main contributing domains without revealing sensitive details on a public screen.

Input status

New, missing, stale or corrected input status.

Maturity and version

Current data-maturity state, algorithm version and material version-change notice.

CHI must not be optimized like a game

The goal is not to maximize a number at any cost. Nily must not encourage excessive exercise, food restriction, repeated measurements, unnecessary tests or unsafe medicine behaviour to improve CHI.

Programs and insights should focus on practical health actions and individual goals, not score manipulation. Missing a day must not trigger a punishment or dramatic score penalty simply to create engagement.

Safety operates outside the score

Urgent symptoms, explicit safety responses, serious medicine concerns and crisis indicators require direct action even if CHI is high, stable or improving. CHI must not average away a critical signal.

For a possible emergency in India, call 112 or go to the nearest emergency department. Review Nily's Safety Guidance. If you may harm yourself or cannot stay safe, use Mental-Health Safety Guidance and immediate human support.

CHI should explain uncertainty honestly

Data can be incomplete, self-reported, device-dependent or collected under changing circumstances. The interface must show uncertainty through plain-language data maturity and source status—not a false decimal precision or a hidden confidence claim. Do not compare CHI scores between users as if they have identical inputs, context and measurement quality. Personal change is the primary use.

Validated assessments remain separate

If a user completes a validated screener or established clinical calculator, Nily preserves its name, scoring, timeframe and limitations. The result is never relabelled as CHI, and CHI never implies it reproduces the instrument. Explore Free Health Assessments and Checkers

You control which supported signals contribute

The CHI settings show connected sources, current permissions, contribution status, last-used time and the consequences of disconnecting. Revoking future contribution is straightforward and is never bundled with marketing consent. Historical recalculation, deletion and algorithm-version migration follow clear rules—a past trend is never silently recomputed to look as if it always used the new method.

CHI data is sensitive health information

The composite score, domains, inputs, missingness, trends and inferred states can reveal sensitive information even without raw entries. Nily does not use CHI for advertising audiences, lead scoring, insurer or employer decisions, pricing, eligibility, public ranking or general session replay.

Frequently asked questions

What does CHI stand for?

CHI stands for Composite Health Index. It is Nily's longitudinal view of selected supported health and wellbeing signals.

Is CHI a medical score?

No. Unless an exact future intended use is separately validated and approved, CHI is a product tracking and reflection index—not a diagnosis or clinical-risk score.

How is the Nily CHI calculated?

The current version uses supported, consented inputs, applies quality and freshness rules, calculates approved domain contributions and creates an explainable composite view. The app must identify the algorithm version.

Is CHI a health score calculator?

No. CHI is a versioned longitudinal product view built from supported, consented inputs. It is not a diagnostic calculator, medical clearance or validated disease-risk score, and it is not meant to be run once like a one-off calculator.

Which data contributes to CHI?

Only inputs listed in the current approved CHI registry and enabled under the user's choices. The settings must show source, contribution status and last-used time.

Why is my CHI in Building state?

The available supported information has not yet met the approved maturity rules for an initial pattern. Building does not mean poor health or failure.

What do Early, Moderate and Stable mean?

They describe how established the available personal data pattern is under the current method. They do not mean unhealthy, average or healthy.

What is a good CHI score?

CHI should not be reduced to a universal good-versus-bad target. Review your personal trend, contributing domains, maturity, missing data and relevant professional context.

Can CHI diagnose diabetes, PCOS, depression or another condition?

No. Diagnosis requires appropriate individual assessment. Validated screeners and laboratory results retain their own separate meanings and limitations.

Can a high CHI mean I am safe?

No. Severe symptoms, urgent changes and safety concerns require direct action regardless of the score.

Why did my CHI change?

The interface must explain whether supported inputs changed, became stale, were corrected or were processed under a new algorithm version.

Can I improve CHI by checking in more often?

More entries can increase context when useful, but quantity is not automatically quality. Do not submit artificial data or unsafe behaviours to chase the score.

Can I compare my CHI with another person?

CHI is primarily a personal longitudinal view. Different inputs, context, devices and data quality make simplistic comparisons misleading.

Can a doctor see my CHI?

Only through an explicit authorized service or sharing action. CHI does not replace the underlying data or the professional's clinical record.

Will CHI be used for advertising, insurance or employment?

It must not be used for advertising audiences or insurer and employer decisions. Current permitted uses must be stated in Nily's privacy and data-use notices.

Can I delete or disconnect CHI data?

The product must provide clear source-disconnection and applicable correction, export and deletion controls, including how historical scores are handled.

How can I contact Nily?

For support or privacy questions, email care@nily.health. For business or partnership enquiries, email Info@annotatory.com.
