The Nymi iOS SDK allows developers to create applications for the Nymi wristband. The Nymi band aims to allow individuals with persistent identity via authentication using a uder's unique ECG. The SDK allows developers to use "native" and "net" flavors of the Nymi Communication Library. The native flavor is for directly interacting with physical Nymis, and the net flavor allows interaction with a Nymi ecosystem daemon (ecodaemon). The Nymi iOS SDK is written in Objective-C.
