NES Health / E4L GEM – The Only Wrist Device that Measures and Corrects

The NES Health GEM, also known by its new name, the E4L, is a wearable wellness device that you simply wear on your wrist. Its unique selling point is that it not only measures but also delivers corrective frequencies —something no other wrist device does in this way.

What does the GEM do?

Wearing the GEM provides natural insights into your daily well-being. The device:

  • Measure energy dynamics through your wrist
  • Provides insight into emotional patterns
  • Follows your sleep rhythm

-> Corrects : Emits gentle light and electromagnetic frequencies, intended to support your balance

This combination makes the GEM unique: it is the only device that both records and corrects via the wrist.

Works together with the updated E4L app

The GEM synchronizes with the E4L app, where you can find all your data clearly displayed.

This is what you see:

  • How to move your energy through the day
  • Which emotions have an influence
  • Where you could use extra support
GEM measures and corrects energy, emotions and sleep


Because the device both measures and corrects via your wrist, it offers more than just data --> It gives you a practical form of daily support and you simply 'FEEL GOOD'

Personalized 24-hour cycle in the background

The GEM automatically runs a personal 24-hour cycle.
The device starts the supporting programs that are best suited to that time according to traditional Chinese medicine at any time of the day.

This happens all by itself — you don't need to set anything up.
