About the project

At Radiotech, we believe music belongs to everyone - not just those who grew up taking lessons. As a product company inside the Gismart ecosystem, we've spent years building apps that make music feel approachable, fun, and deeply human. With 23 apps across iOS and Android and over 500 million downloads worldwide, our products have found their way into the hands of musicians, beginners, and curious souls across the globe. We see music as a universal language. Our job is to make sure more people can speak it.
