Digital Fitness Tracker Watch

Tracking steps tells you what you did — this fitness tracker measures continuous HRV and blood oxygen to tell you what your body is ready to do, delivering a daily recovery readiness score so every training decision is backed by biology, not guesswork.

Why it works: Overnight, the watch continuously reads your heart rate variability and blood oxygen levels, then translates that raw biometric data into a single morning readiness score — so you know whether to push hard or pull back before you ever lace up.

What it does

• Daily readiness scoring. Wakes you with a clear go/recover signal grounded in last night's HRV data, not yesterday's workout plan.
• Continuous SpO2 monitoring. Tracks blood oxygen around the clock so you can spot recovery patterns over time.
• Step, activity, and calorie tracking. Captures all the standard movement metrics alongside your deeper biometrics in one clean dashboard.
• Sleep stage analysis. Breaks down your night into light, deep, and REM phases to show exactly where your recovery is — or isn't — happening.

How to use

Wear it to bed and let it work overnight. In the morning, check your readiness score before you decide how hard to train. Over time, the data builds a personalized baseline so the guidance keeps getting sharper.
