Medical device or wellness gadget: how health wearables are regulated

The difference is the purpose the maker states. A medical device is meant to diagnose, prevent, monitor, treat or relieve a disease or condition. A wellness gadget is meant to support general health, such as counting steps, tracking sleep or nudging a user to exercise. The same sensor can sit on either side of the line depending on what the box and the app say it is for.

This is why two similar watches can face very different rules. One that promises to detect an irregular heartbeat is making a medical claim. One that only shows a heart rate for workouts is not. Lawyers call this the intended use of the product, and it is the idea that drives almost everything in this area.

A recent live case is Temple, a brain-health wearable, where doctors online questioned its blood-flow claims and the founder replied that it is a fitness gadget and not medical equipment.

Medical devices are regulated under the Drugs and Cosmetics Act, 1940, through the Medical Devices Rules, 2017. The Central Drugs Standard Control Organisation (CDSCO), led by the Drugs Controller General of India, runs the system. State licensing authorities handle some of the work for lower-risk products.

The Rules came into force in January 2018 and were extended step by step to cover more kinds of device, with all devices brought under licensing by 2022. As of November 2026, a company selling a regulated device must hold the right licence or registration, follow quality management rules and meet labelling and reporting duties.

The Rules sort devices into four classes by risk, using the intended use, the risk of harm and other factors set out in the First Schedule. CDSCO publishes lists that place named devices in each class.

Higher classes face more scrutiny, and the licensing authority differs by class. Per the commentary available, lower classes are handled by state authorities and higher classes by the central authority. Always check the current CDSCO notices for the class of a specific product.

• Class A: low risk. Simple items such as thermometers and some dressings.
• Class B: low to moderate risk. Examples include some monitoring devices.
• Class C: moderate to high risk. Devices where a fault could cause serious harm.
• Class D: high risk. Implants and life-supporting devices are typical examples.

India has not drawn a separate bright line for consumer wearables. Legal commentary has noted that CDSCO has said little about smart wearables, so a device marketed purely for fitness and wellness has generally avoided the medical device rules. Many smartwatch makers add that their readings are not for medical use, which helps keep them on the wellness side.

The reverse also happens. GOQii, an Indian health-tech company, obtained CDSCO registration for some of its wearables in December 2020, since those products were meant to detect health issues. That is the usual route for a firm that wants to make medical claims: register the device and accept the licence and quality duties that come with it.

Software gets its own attention. CDSCO has published guidance on medical device software under the 2017 Rules, and reports say general wellness software is outside the definition while software that claims to diagnose or monitor disease is inside. Check the final text on the CDSCO site for how a particular app or feature is treated.

Three layers of law apply to claims. The first is the medical device regime: a claim to diagnose or treat disease pulls a product into licensing. The second is the Consumer Protection Act, 2019, under which the Central Consumer Protection Authority can act against misleading advertisements and order them withdrawn, with penalties. The third is the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954, which bars advertising that suggests a product can cure or prevent certain listed diseases.

In practice that means a wellness brand can say its product helps users track sleep or stay active, and should avoid words like cure, treat, diagnose or detect disease unless it holds the right registration and evidence. Strong claims about brain function, blood flow or disease risk invite scrutiny from doctors, regulators and rivals alike.

Wearables collect some of the most personal data a person has: heart rate, sleep, location, sometimes blood oxygen. The Digital Personal Data Protection Act, 2023 applies to such data. Its Rules were notified on 13 November 2025 and phase in over about 18 months, with most duties from around May 2027.

A company will need clear consent, a plain-language notice, limits on how long data is kept, and security safeguards. It will also need to tell users and the Data Protection Board of any breach once those duties are in force. Health data is not given a separate category in the Act, but regulators are expected to look closely at it.

Medical registration takes time and money. A company has to classify its device, build a quality system, prepare technical files, wait for a licence and keep reporting after launch. For a young hardware startup, that can add months before the first sale.

The wellness route lets a product ship sooner and test demand. The trade-off is a ceiling on what the company may say, and a risk that a doctor or regulator reads its marketing as a medical claim. Some firms start in wellness and move to registration for later models once the evidence is in.

A product sold as wellness that is later found to make medical claims can face action on several fronts. CDSCO can treat it as an unlicensed medical device and ask for it to be withdrawn from sale. The consumer authority can order misleading advertisements to be pulled and can impose penalties. Retail platforms may also delist the product after a complaint.

There is a reputational cost as well. When doctors publicly question a claim, the debate spreads quickly on social media, and customers who paid a premium price feel misled. Clear, modest wording on the product page, honest limits on accuracy and a plain statement that the product is not for diagnosis are the usual defences. Companies planning bolder claims should plan for evidence, such as validation studies against a recognised clinical method.

When a health wearable is in the news, ask five things. What exactly does the maker say it does? Has it said whether it is a medical device? Does it hold a CDSCO registration? What clinical evidence is cited, and by whom? And does the price or the marketing suggest more than the product can prove?

Disputes often start when a founder says 'this is not a medical device' while the product page describes health effects. This guide is general information and not legal advice, so a company planning a launch should check with a regulatory professional.
