Difference between mySASY and Elonga

What is the difference between the mySASY and Elonga systems, especially when both projects come from the same background and often the same people? They are two completely separate systems with different goals, functions, and outputs.

1. The Fundamental Difference — Different Focus

Elonga — health & longevity

• for active people who want to improve their health and slow aging

• focuses on lifestyle, sleep, stress, and overall body functioning

• offers simple, easy-to-understand daily outputs
  (what to do today, how to move, when to slow down)

mySASY — performance & efficiency

• primarily for athletes and performance-driven users

• aims to optimize training and athletic performance

• suited for those who want complex, detailed HRV analysis

2. What Does Elonga Do? (health, lifestyle, simple outputs)

Elonga:

• measures overall physiological state using spectral HRV analysis

• evaluates stress, recovery, readiness, functional age

• provides a clear morning overview after a simple 3-minute measurement

• offers a weekly movement plan with activity recommendations

• helps improve health, sleep, resilience to stress, and prevents lifestyle-related issues

Elonga is designed to be intuitive and easy to use for everyday active people.

3. What Does mySASY Do? (performance, training, sports efficiency)

mySASY:

• built for users who want to maximize athletic performance

• supports planning and managing training load

• offers more complex HRV metrics and deeper analysis

• ideal for performance athletes, professionals, coaches, and data-driven users

mySASY is suitable for those who want in-depth HRV and training-load interpretation.

4. Why These Systems Should Not Be Directly Compared

• each has its own parameters and scales

• outputs serve different purposes: health vs. performance

• the same morning may show different results and both can be correct

There is no meaningful “conversion” between Elonga and mySASY outputs. They are built for different contexts.

5. Why We Do Not Recommend Using Both at the Same Time

Using both systems simultaneously can cause confusion because:

• both require morning, resting-state measurements

• measuring with both back-to-back can:

  • break standardization

  • complicate interpretation

  • create unnecessary stress (“why are the results different?”)

We recommend choosing one system and sticking with it consistently.

6. How to Choose Between Elonga and mySASY

Choose Elonga if you want to:

• improve health, sleep, recovery, stress management

• focus on long-term longevity and overall wellness

• receive simple daily recommendations

• avoid complex sports metrics

Choose mySASY if you:

• are an athlete or train for performance

• want to fine-tune training volume, intensity, and timing

• want detailed HRV analytics

• don’t mind deeper interpretation and more complex data

Summary

• Elonga and mySASY share the same roots but have different goals.

• Elonga: health, lifestyle, simple intuitive outputs.

• mySASY: performance, detailed training analysis.

• Direct comparison doesn’t make sense — they use different logic and data interpretation.

• Using both at the same time is not recommended. Choose the system that fits your goals.
