When setting up iECHO GPA do I need a username and password to enter details?

No, initially you can manually enter all reuqired details and start recording and sending data immediately.  However, you can use your webECHO username and password to download your details directly from webECHO into the App.  For further details refer to the iECHO GPA User Guide or contact us at inquiries@jet-care.com
