The story of your heartbeat step by step

Morning Measurements

Put on Elonga’s unique optical sensor each morning for just a few minutes. Measurements are done under standardized conditions, right after waking up, so factors like coffee or breakfast won’t affect your results.

How It Works – Optical Sensor

Elonga’s sensor shines light through your blood vessels and monitors the intervals between heartbeats to the thousandth of a second, giving you precise HRV (heart rate variability) readings.

The World’s Most Accurate Spectral HRV Analysis

Unlike most smartwatches that track activity, Elonga focuses on your body’s internal state. Spectral analysis usually takes 20 minutes, but our algorithm does it in just 3 minutes—showing you what’s happening in your autonomic nervous system.

Why 3 Minutes Is Enough

We Diagnose the Autonomic Nervous System

The autonomic nervous system (ANS) has two branches: sympathetic (stress) and parasympathetic (recovery). Everything you do affects its activity, and understanding it helps you optimize your health.

Your Results in the App

Elonga evaluates your autonomic nervous system (ANS) and provides clear insights into its condition. The sympathetic branch indicates stress, while the parasympathetic branch reflects regeneration. To simplify, we introduce Readiness, an aggregate value representing both stress and regeneration. Over time, this helps you understand if your lifestyle choices contribute to long-term health.

Functional Age

Do your efforts lead to youthfulness?

We compare your results with those of your peers to determine your functional age. This metric shows whether you're on the right path for long-term health.

On it, you can see if you are going in the right direction for the long term.

Readiness

We recommend a specific activity every day.

Each day, Elonga suggests an activity tailored to support your health. Our recommendations are based on long-term monitoring and are designed to be optimal for you.

We also plan activities on a weekly basis to keep you moving

The motion recommendations are compiled by our mathematical model at the suggestion of physiologist and co-founder of Elong, Radim Slachta, who has also collaborated with WHO.

Stress

Stress as a silent killer.

Elonga helps you monitor stress daily, identifying when it's becoming excessive.

The app also provides guidance on what helps reduce stress and what to avoid.

State of health

Calm down before the disease manifests.

Your body often combats illness before symptoms appear. By relaxing in time, you can potentially reduce the duration of illness and recovery by up to half.

Fitness Score

Are you making progress?

Elonga tracks your fitness changes over time, helping you understand if you're on the right path.
