Frequently asked questions
What are Hiyd Readings?
Health is completely personal. Everybody's body needs different amounts of sleep, food, and exercise to achieve very specific personal goals. Do you workout better in the morning? Do you eat before or after your workouts? How are your energy levels after a workout? Hiyd Readings will analyze your habits and will optimize your health.
How does the Hiyd tracker attach to my watch?
Our microsuction surface attaches to the bottom of any watch. It's adhesive-free, meaning you can put it on any watch without leaving a mark.
What about when I work out or sleep? I don't wear my watch then.
Hiyd's got it covered. We offer our SoftBands – both in textile and soft touch silicone – that are designed for seamless switching of the tracking as you switch from the office to the gym and back out again. All tracking goes directly onto the app, so you're not switching between apps to get insights.
When do orders start shipping?
Shipping is slated for July 2026, with pilot batch orders closing in June.
What else should I know about these SoftBands?
We don't have notifications on the tracker, so you can focus on your workout – or your work – without distractions. It's also low profile and super slim, allowing for all kinds of movements without contacting the tracker – no accidentally hitting buttons, or butt dialing, or bumping it into people and equipment. It's just a part of you.
