# WitU

> WitU is a premium ("fine-jewelry") ecosystem of wearables for health, recovery and longevity. Its key differentiator is a dual ECG system (an electrode on the case plus an electrode on the butterfly clasp) and integration of blood-test results for personalized insights. The device's core features work without a subscription. WitU is a wellness device, not a medical device — its insights are for informational purposes only and do not constitute medical advice, diagnosis or treatment. Prices are in USD; sales begin in 2026.

## Core technology
- Dual ECG: a real electrical signal from the heart versus optical heart-rate estimation (PPG), which loses 30–40% of its accuracy during movement.
- DCI (Data Confidence Index): sensor accuracy × 0.4 + blood tests × 0.3 + observation duration × 0.3. With optical smartwatches it starts at ~60%; with a WitU device and blood tests it reaches up to 100%.
- Blood tests: upload a PDF/DOCX from your lab and the AI recognizes biomarkers (ferritin, vitamin D, TSH, cortisol) in about 30 seconds.

## How it differs from the competition
- A real ECG versus optics (PPG) on Whoop, Oura and Apple Watch.
- Core features work without a mandatory subscription (unlike Whoop and Oura).
- It factors in blood tests (ferritin, vitamin D, TSH, cortisol) — no competitor does this.
- Fine-jewelry materials (titanium, silver, gold, platinum) instead of polymer.

## App plans (the subscription is optional; the device works without it)
- Free — $0: core monitoring forever (heart rate from your camera/watch, steps, basic DCI, 7-day history).
- Basic — $4.99/mo: Apple Watch/Garmin/HealthKit integration, 30-day history, reports.
- Premium — $9.99/mo: AI insights, blood-test uploads, unlimited history, advanced HRV.
- Pro — $19.99/mo: detailed PDF reports, CSV/API export, family access (up to 5), priority support.
14-day free trial. Annual billing = two months free. Secure encrypted checkout. https://witu.life/pricing

## Comparisons (one per competitor, with a takeaway)
- WitU vs Whoop — https://witu.life/vs-whoop. Takeaway: you pay Whoop for recovery analytics — WitU gives you ECG-grade accuracy with no subscription fee; Whoop is strong on community.
- WitU vs Oura — https://witu.life/vs-oura. Takeaway: WitU has its own Ring, and if you need ECG there is a bracelet in the same ecosystem; Oura remains the benchmark for sleep.
- WitU vs Apple Watch — https://witu.life/vs-apple. Takeaway: if you want an all-in-one smartwatch, Apple is unmatched; if you want continuous ECG, long battery life and biochemistry without being tied to iOS, that's WitU.
