dip (v2)

The world's first women's anemia tracker

Anemic woman lying down exhausted

20% of women are anemic, causing life altering issues. It is caused by a lack of hemoglobin in the body. There are currently no consumer devices on the market that allow people to self check their hemoglobin levels meaning they rely on inconvenient doctor appointments.

Changing the wavelenth factor on the sensor means we can track hemoglobin saturation in the blood through the skin.

Typically, women's watches have a white dial. By having 0.5mm, white ABS, capacitive panel it allows a bright LED behind it to shine through.

LEDs can be used to shine through the skin and calculate the Hemoglobin (Hb) saturation.

Dip render charger

Charging through pogo pins is much faster than wireless and more convenient that standard wired charging. The circular shape allows the user to charge the device, avoiding the possibility of misalignment.

Dip render strap

Customising the strap style and colour gives women the option to stylise Dip.

Machine injection moulding allows the versatility and low unit cost suitable for a mass produced product.

Research shows that women do not want the aesthetic of their watch to be overly saturated with features. The simplified information allows the dial to remain dainty and feminine.

Dip is a wristband paired to a mobile app, empowering women to take control of anemia. Non-invasive sensors measure hemoglobin levels and combine with user lifestyle data to help women understand the impending impact of their choices on their health. Real Time personal tracking saves time by reducing the frequency of blood test appointments.

How does Dip work?
