Who SpryFuel was built for
spryfuel is a subscription streaming platform - not a supplement - offering a library of 750+ frequency-based audio programs (using psychoacoustic tones and binaural beats) aimed at sleep, stress reduction, focus and relaxation. It suits people curious about sound/frequency-based wellness practices who want an app-based routine over pills or capsules.
