Once you have signed up for the BioCoach membership, you will have an account created within the BioCoach database. Simply head to the Apple Store, or the Google Play store, and download the BioCoach app. Upon loading, the app will ask for your email / phone number. Be sure to use the same email and phone number that you used when you purchased your meter/membership. If you have an account, you will be asked to confirm your contact information and create a password. If it says no account exists for your email, email support@biocoach.io for assistance.
