Real-time hydration intelligence

A wristband that knows when you’re thirsty.

NUVIO Band continuously senses your hydration levels, predicts when you’ll need water, and nudges you before your performance drops – whether you’re in class, on the field, or gaming late into the night.

Beyond “drink more water”. Meet your real baseline.

NUVIO Band translates complex biosignals into clear, friendly insights: how hydrated you are, how fast you’re losing fluids, and how to get back to your personal sweet spot.

Continuous hydration index

Track your hydration level as a live score that updates throughout the day. No manual logging, no guesswork, non-invasive monitoring. Just glance for updates.

Auto-calibrated to your body over time
🔔

Predictive Alerts

Learns and analyze trend data and contextual factors, providing proactive warnings for impending dehydration, not just reactive notifications

Smart learning, predictive highlights

Contextual Data

Automatically integrates data from the mobile phone's sensors (e.g., GPS for activity, weather API for ambient conditions) to refine the hydration model and alert accuracy

Ambient data, weather integration
📋

Personalized Rehydration Plans

Delivers specific, quantitative recommendations on the volume and type of fluid needed, tailored to the user's real-time fluid deficit.

Tailored recommendations for you
🌙

Sleep Hydration Tracking

Monitors nocturnal fluid loss and provides a "Morning Hydration Readiness" score, a key metric for starting the day optimally hydrated.

Sleep-safe, ultra-light design

Athlete Mode

An enhanced setting for high-intensity activity, offering real-time fluid loss rate (mL/hour) and sodium loss estimation for critical performance management.

Performance-aware alerts

Science on your wrist. Signals in your pocket.

NUVIO Band combines optical sensing, skin-contact electrodes, and machine-learning models to estimate hydration — all passively, while you live your life.

Step 01
Signal capture

Multi-wavelength LEDs and micro-electrodes measure how light and tiny currents move through your skin — signals that shift as your hydration level changes.

Step 02
On-device processing

HYDRA’s sensor hub filters noise (movement, temperature) and runs edge-optimized models tailored to your baseline over time.

Step 03
Personalized insights

A simple 0–100 hydration index syncs to your phone and watch — plus trends, streaks, and “hydrate before…” predictions for key moments.

A dashboard that feels like a game – not homework.

The NUVIO app turns hydration into something you actually want to check: streaks, adaptive goals, and smart reminders that don’t spam or shame you.

Build “hydration streaks” that actually matter — tuned to your schedule, climate, and activity. See how days at school, training sessions, or exams impact your hydration pattern, and let HYDRA auto-adjust targets when it’s hotter or you move more.
