Quell Mobile App

The Quell Relief mobile app for iOS and Android gives users the ability to control their therapy and provides insights into their therapy, sleep, activity, and pain.

Quell Device

The Device

The Quell wearable pain relief device from NeuroMetrix fights chronic pain by stimulating nerves in the upper calf, which send neural pulses to the brain. This causes the brain to release natural opiates that block pain signals and deliver widespread pain relief throughout the body. Quell is a new alternative to treating chronic pain, and the first device of its kind approved by the FDA for use during sleep.

The Mobile App

The Quell mobile app lets the user:

  • Start and stop therapy sessions and adjust the intensity of therapy.
  • Customize therapy, including stimulation patterns and sleep modes that work best for the users' pain level.
  • Track and review detailed insights about therapy, sleep, pain, and activity.

It also displays the battery level and the remaining life of the device’s electrodes, and it links directly to Quell’s online store, making it easy to replace electrodes.

The Quell app syncs with the device via Bluetooth LE. Both iOS and Android versions are available.
