To create an account simply tap the 'Sign Up' button on the first screen. Fill out the form with your information and click 'Next'.
After filling out your information, you will be asked to choose a plan. See our pricing guide for more information on available Mapview plans.
Lastly, you will be asked if you would like to 'Choose Groups to Sync'. This will geo-code contacts from your device's address book. You can skip this step and do it later if you do not want to import data right away.
