Sleep soundly and relieve stress and anxious thoughts without drinks or pills. Thync uses neurostimulation to relax you in minutes.

App ONLY works with the Thync Relax Pro System.

Thync Relax Pro consists of 3 components:
1) The App – compatible with iPhone 5, 5s, 6 and 6s, 7 and 7 plus, and iOS 10.0 and higher.
2) The Thync Pod.
3) Thync Pads.

Featured Neurostimulation Programs:

Deep Sleep: Reach a calm, peaceful state and improve sleep.

Deep Relax: Let go of anxious feelings and slow down your thoughts.

The App enables users to select and control Thync Neurostimulation Programs.
These are proprietary algorithms that use safe, low level electrical stimulation to activate specific nerve pathways on the head and neck. These pathways communicate with areas in the brain that help control stress levels, mood and sleep quality. Thync Relax Pro delivers carefully constructed stimulation patterns that tap into your body’s own mechanisms to relax, improve mood and sleep better. Nerve stimulation approaches have been used for decades and have shown to be safe with substantially lower levels of side effects than pharmaceuticals.

Science and Safety
Thync science is proven and has been validated in 3 publications using a combination of biometric and biochemical assays along with clinical psychological surveys. These studies demonstrate a neurostimulation method that can lower stress and anxiety as well as elevate mood and sleep quality.

Thync Relax Pro produces output levels that are approximately 1/5th of the current output of standard over-the-counter TENS and EMS/PMS devices. Nerve stimulation has been used for decades and has a low-risk safety profile. An independently conducted, extended use study (100 participants and 1800 sessions) showed that the incidence of any adverse effects were equal to a sham protocol (no stimulation). In addition to this safety data, Edition One has over 2,500,000 minutes of use from customers supporting the conclusions from this safety data.

Thync Relax Pro is considered a low-risk wellness product and has been exempted by the FDA from its medical device regulations and approvals.
Using Thync alongside a healthy lifestyle can lower anxiety. Thync is a wellness product not intended to treat psychiatric disorders such as, but not limited to, generalized anxiety disorder, social anxiety disorder, and panic disorder. Thync is not a substitute for professional medical care.

Ratings and Reviews

So expensive for such a buggy device


You have to maintain a near $50 per month subscription just to get to use the app and device. And I would like to do just that. Except I can almost never can get my iPhone to connect to the device! Tech support has been awful. My goal of reducing stress has only increased it.

Vibe product is good, App needs some work


I've loved using the Thync Vibe for meditation, and was surprised at how effective the e-pulsing is at calming wayward thoughts. However, the app works well enough to control the device, but is missing some basic functions that users are accustomed to finding in app design. The timer only counts upward: users can't set a specific interval, so I'm often stopping short of my desired session. Other than a drawing, there's no real guide for positioning the Thync Vibe, so sometimes I feel less pulse than others. Also, in-app purchases only support the subscription models, not unlocking the device & pads. My experience with Thync feels like the engineers spent great effort at product development for the Vibe, but don't have the background for refining the user experience. It's a pricey device for muddled communication.
