An estimated 1 out of 3 adults worldwide struggle with sleep. Their brains find it difficult to shift into a lower gear to reach Theta and Delta brainwaves which are necessary for sleeping. For centuries it has already been known that sound can change the mental state of the brain. Sound can cause anxiety, it can bring calmness, and it can also affect sleep. There is a solid science behind why this exactly happens, and it all has to do with brainwaves. Brainwaves are the electrical signals the brain uses to process information, think, and communicate with the body. Brainwaves run at different speeds during different mental states. When we’re in a deep sleep, it predominantly runs at 1 to 4 Hz; when dreaming, it runs at 4 to 8 Hz; when awake, it runs at 8 to 12 Hz, and when highly alert, it runs at 12 to 100Hz. So how does sound affect brainwaves? Brainwaves are frequencies, and sound is also frequencies. When a person listens to a sound frequency, the brain synchronizes with that frequency. The brain starts pulsing the electrical form of the frequency, brainwaves. For example, when a person listens to a pulsing sound of 4 beats per second, the brain starts pulsing a 4 Hz Delta brainwave, which is the signal for sleeping. Scientists have used this technique to help people sleep with some success. It has turned out that the brain resonates well with certain frequencies and not so well with others. Albert La Grange has spent more than 12 years of research and has done over 6000 sound frequency tests. He discovered the exact sound frequencies that resonate well with the brain and that enable a person to fall asleep. To share this discovery with others, an app called Evolutioner was created where these frequencies are embedded in ambient and cinematic music sessions. The user simply listens to a 12-minute music session to fall asleep. No other action is needed for it to work. People can now download the Evolutioner app from the App Store. The app is already being used by more than 50000 people every day and night. If you have issues with falling and staying asleep, download the Evolutioner app and try it out tonight.

Our Matcha Mission We seek to source and provide the world’s best matcha tea, build lifetime relationships, share matcha culture, give back more than we take, and better the lives of our customers and our community. Our aim is share our knowledge on the merits, health benefits, and spirit of matcha. A focus on quality We decided to form a company to identify and import the highest-quality matcha available and provide tea lovers everywhere with the world’s best matcha tea. Like most consumers, we were astounded at the price tags of ultra-premium matcha in Japan and realized that added costs of import would put it beyond the reach of many American consumers. We wanted to change that. We found that we liked the better grades of thin tea for everyday use and were willing to pay more for some of the medium-quality ceremonial grades to use for special occasions. We choose to import only those products that met our standards for color, aroma, and flavor. Matcha Kari’s teas come from the fields around Uji City near Kyoto, Japan, the birthplace of Japanese tea traditions. Tea produced in the Uji region is prized for its bright color and rich flavor and is often considered Japan’s best. DOWNLOAD THE APP AND STAY UPDATED WITH BENEFITS AND OFFERS. FREE SHIPPING OVER $59

Verdict
The clearest difference is in-app purchases: Matcha Kari at none against Evolutioner's 5. Matcha Kari also leads on review sentiment (100% vs 69%) and rating (5.0 vs 4.8). Evolutioner's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (1.7K vs 1). On price, ads, device support and iOS requirement there is nothing between them.
