Most online courses are designed for phones, tablets, or computers since those screens are bigger and easier to navigate. Smartwatches have tiny screens, so watching videos or reading detailed content can be tricky. However, if BMF.io offers audio lessons or short, bite-sized content, those might work pretty well on smartwatches—perfect for learning on the go. Some smartwatches also support apps or browsers, so you might access course materials, but it's probably not the smoothest experience.
