Inspired by the work of Dr. Masaru Emoto, the eFlaska app is combining ancient knowledge with modern principles of frequency and vibration using the Quantec Technology to bring your water into the revitalized and energized state of your need and intention. Simply select one of the vibrational programs, take a photo of your water that you want to structure, wait until the activation process is over and at the end stir or share shake for three seconds to finish the water revitalization. There are five different vibrational programs available to serve your needs and intention with its unique and specific frequency: Spring water, Morning boost, Vitality water, Yoga & meditation and Sweet dreams. As a bonus there are also vibrational programs intended specifically to structure the water for Pets & Plants as well as your shower and bath. The eFlaska app allows and encourages you to share your structured water photo and experience via various platforms with you friends.
