Wrizap

“Turning hypertension from a silent bane into a managed condition.”

A MEMS-based wristband that monitors blood pressure continuously — no cuff, no clinic visit, and it works without internet.

The problem

Hypertension is called the silent killer because it rarely announces itself — and the tools we use to catch it are too occasional to matter.

  • In 2024, an estimated 1.4 billion people aged 30–79 had hypertension — and fewer than 1 in 5 had it adequately controlled.⁴
  • 46% of adults with hypertension don't know they have it.⁴
  • More than three-quarters of adults with hypertension live in low- and middle-income countries⁵ — often where clinics are far away and internet is unreliable.
  • A cuff reading is a single snapshot. It misses night-time spikes, daily patterns and the moments that actually carry risk.

Our solution

A MEMS-based wristband that monitors blood pressure continuously — no cuff, no clinic visit — and works without internet.

“Digital health shouldn't stop where the network does. Wrizap is built to bring continuous blood pressure monitoring to remote areas of India and the world — places that have been left out of the digital health revolution.”

Features

What Wrizap does

Built for places the internet doesn't reach

On-device processing

In development

Readings are computed on the band's own microcontroller; no cloud needed to produce a result.

Offline-first storage

In development

Readings are stored on the device and synced later whenever any connection becomes available (store-and-forward).

Phone without data

In development

Pairs with a phone over Bluetooth Low Energy, which needs no internet or mobile data.

Alerts that still get through

In development

Critical readings can trigger an SMS alert to a family member or health worker over a basic mobile signal.

Low-power design

In development

Long battery life for areas with irregular electricity.

How it works

How Wrizap works

  1. Wear

    A lightweight wristband with MEMS pressure sensing.

  2. Track

  3. Act

    Trends and alerts shared with the user and their doctor.

Who it's for

Built for

  • People living with hypertension
  • Rural and remote communities
