My phone doesn't have a 3.5mm headphone jack, will a Nano be made for my phone?

You betcha!

Center Health's Nano is currently only available for phones with a 3.5mm headphone jack or iPhones with an adapter / dongle. We're working on an Apple Lightning and USB-C version of the Nano and look forward to launching these in the coming months. Stay tuned! Meanwhile, if you have an iPhone, you can use your Center Nano with Apple's 3.5mm to Lightning adapter dongle with the Nano :)

Thanks for your patience!
