Yes. The app is free and works with just your phone or your existing watch — Apple Watch, Garmin, Samsung, Polar. The bracelet adds high-fidelity ECG, but it's not required to get started.

Upload a PDF or DOCX from any lab. The AI reads your biomarkers in 30 seconds and factors your real biochemistry into your recommendations. This is what sets WitU apart from other trackers.

A dual ECG system with additional electrodes (patent pending) delivers accuracy roughly 10% higher than optical PPG sensors. Add blood-test integration and an open ecosystem — neither Whoop nor Oura does that.

Recommendations are generated by algorithms from your data and are for general wellness and informational purposes only. WitU is not a medical device and does not replace professional medical advice — a disclaimer appears on every page with recommendations.
