CoWIN, ABHA, Aarogya Setu: understanding India’s digital health apps and how they connect

Three names, three purposes, one ecosystem and a lot of confusion about which does what. Here is the clearest explanation of how India’s digital health infrastructure actually fits together.

CoWIN, ABHA, and Aarogya Setu are India’s three most visible government digital health platforms and they are genuinely confusing to most people because they are connected, partially overlapping, and have each evolved significantly since COVID-19. This guide explains what each platform does, how they connect to each other, and where apps like Seht fit in relation to India’s national digital health infrastructure.

What you’ll learn:

  •  What CoWIN is and what it does now that COVID vaccination is complete

  •  What ABHA is, how it differs from Aarogya Setu, and how to create one

  •  What Aarogya Setu 2.0 changed the complete pivot from COVID tracker to PHR app

  •  How all three connect through ABDM (Ayushman Bharat Digital Mission)

  •  Where Seht fits and what it does that the government apps don’t

The three platforms what each one actually does

Platform	What it is	Primary function now (2026)	Relation to the others
CoWIN (cowin.gov.in)	Government vaccination registry built during COVID-19	Stores and provides access to vaccination certificates (COVID-19 and other national programmes)	Integrates with Aarogya Setu and DigiLocker; vaccination data can be linked to ABHA
ABHA (Ayushman Bharat Health Account)	Your government-issued digital health ID (14-digit unique number)	The ‘key’ to India’s national health infrastructure presenting your ABHA number at an ABDM-registered facility links that visit’s records to your account automatically	ABHA is the identity layer; Aarogya Setu 2.0 is one app that uses it; CoWIN can link vaccination records to it; Seht links to it for record syncing
Aarogya Setu	Government mobile app developed for COVID-19 contact tracing; now completely relaunched as Aarogya Setu 2.0	PHR (personal health record) app powered by ABDM ABHA creation, health record access from ABDM facilities, insurance wallet (PMJAY, CGHS, CAPF), Scan & Share for OPD registration	Uses ABHA as the identity layer; can pull records from ABDM-registered facilities; CoWIN vaccination data can be viewed through it
ABDM (Ayushman Bharat Digital Mission)	The underlying national health data infrastructure not an app but the system that connects all the above	Enables consent-based sharing of health records between ABDM-registered hospitals, labs, pharmacies, and insurance systems	The backbone that CoWIN, ABHA, Aarogya Setu, and apps like Seht all connect to

In simple terms:

Think of it this way: ABDM is the highway. ABHA is your driving licence the identity that gets you onto the highway. Aarogya Setu 2.0 is the government’s own car on that highway. CoWIN is the vaccination checkpoint that feeds your immunisation records into the system. And Seht is your personal vehicle that uses the same highway but also goes places the government car doesn’t.

What Aarogya Setu 2.0 changed and why it matters

Aarogya Setu was built in 2020 for one specific purpose: COVID-19 contact tracing. It tracked your movements and proximity to infected individuals. That purpose is now gone, and the app has been completely relaunched as Aarogya Setu 2.0 a fundamentally different product.

Aarogya Setu 2.0 is now a personal health record app powered by ABDM. Key functions:

• ABHA creation and login — create your ABHA ID or log in through the app using Aadhaar face authentication

• Health record access from any ABDM-enabled facility — when you visit an ABDM-registered hospital or lab, those records link to your ABHA account and are accessible through the app

• Insurance wallet — view entitlements under PMJAY, CGHS, CAPF, and private health insurance policies; track claims and coverage

• Scan & Share for OPD registration — scan your ABHA QR code at ABDM-registered facilities for instant registration without paperwork

• COVID-19 tracking, risk status, and contact tracing functions have been completely removed

Where Seht fits in India’s national digital health ecosystem

Seht is an ABDM-certified PHR app which means it connects to the same national infrastructure as Aarogya Setu 2.0, allowing ABHA linking and automatic record syncing from ABDM-registered facilities. The difference is what Seht handles beyond the ABDM network.

ABDM-registered providers cover a growing but still incomplete share of Indian healthcare. As of early 2026, over 438,000 health facilities are ABDM-registered out of an estimated 1.4 million total. The gap neighbourhood clinics, local NABL labs, smaller hospitals in tier-2 and tier-3 cities, handwritten prescriptions from GPs is what Seht fills through its in-app scanner and manual upload.

• Aarogya Setu 2.0 and Seht both do: ABHA linking, automatic record syncing from ABDM-registered facilities, health record access

• Seht additionally does: unlimited multi-generation family profiles (Aarogya Setu handles one person per account), handwritten prescription scanning, paper lab report upload, full offline access, shareable emergency health card without login, trend tracking across years of results

• The practical recommendation: use Aarogya Setu 2.0 as your ABHA interface and government insurance wallet. Use Seht as your complete family health record system that adds everything the government app does not reach.

Common questions about the CoWIN, ABHA, Aarogya Setu ecosystem

Things that frequently confuse families about these platforms:

  ⚠  Aarogya Setu 2.0 no longer does COVID contact tracing, risk status, or vaccine certificate download CoWIN and DigiLocker handle vaccination certificates

  ⚠  ABHA is not an app; it is a 14-digit ID that multiple apps (including Seht and Aarogya Setu) use as an identity layer

  ⚠  Creating an ABHA ID does not automatically move all your records anywhere records only link when you present your ABHA at an ABDM-registered facility

  ⚠  Government apps and Seht are not competitors they handle different parts of the Indian healthcare ecosystem and work best together

Emergency: These are all health administration platforms. In any medical emergency, call 108. Your Seht emergency health card is available offline and shareable to any emergency team.

FAQs

How does Seht connect to ABHA and Aarogya Setu?

Seht is an ABDM-certified app. When you link your family’s ABHA IDs to their Seht profiles, records from any ABDM-registered hospital or lab automatically sync to Seht the same automatic record collection that Aarogya Setu 2.0 provides.
