First, you need a Neosensory account to log in the app.
You may have already created an account when you purchased your Buzz. If that’s the case, just tap “Login” on the first screen of the Neosensory app. If that’s not the case, you can create an account in the app by tapping “Create an account” on that same first screen, and use your email address and a password to complete the process.
If you think you already have an account but don’t remember your password, tap “Login” on the first screen of the Neosensory app and then tap the “Forgot password?” link at the bottom of the next screen.
