💚 The wearables market has a lot of devices.

None of them pay you back.

The scheme above compares six devices across eight parameters: price, ECG, EDA, SpO₂, HRV, screenless form factor, Web3 yield, and battery life.

Two things are immediately visible when you look at it. First - every device makes a different compromise. Better sensors usually mean shorter battery or a much higher price. Second - the Web3 yield column has a checkmark in one row only.

🖤 A few things worth noting on the sensor side:

ECG ensures beat-by-beat accuracy in HRV measurement—a feature available within this product line only on the Apple Watch Ultra and the Wellex Band. Furthermore, there is an EDA sensor that records electrodermal activity, which serves as the sole direct physiological marker of emotional state. Wellex is the only device equipped with both of these features simultaneously.

On battery: screenless form factor is what makes 14-day life possible. WHOOP and Oura have no screen and still top out at 5–7 days. Wellex Band runs PPG continuously at 1 Hz, EDA at 10 Hz, accelerometer at 50 Hz - and still reaches 14 days.

Wellex Band: ECG 🖤 EDA 🖤 SpO₂ 🖤 HRV 🖤 Screenless 🖤 14-day battery 🖤 Web3 yield 🖤

Every other device tracks your health and stops there.

Wellex is where the data starts working for you.
