You can add a new account by tapping the Echofon icon located in the top-left corner to open a drop-down menu, which will show all of the accounts you currently have added to Echofon. Select the ‘Add/Edit Accounts’ option from this list to find the option to add a new account. Once ‘Add/Edit Accounts’ is selected, you will see a new page that lists all of your current accounts. You can select any of the accounts on this screen to view/edit the Notification and Device Sync settings for the selected account.
You can also find the same menu by tapping the Menu icon in the top-right corner of Echofon and selecting the ‘Accounts’ option from the menu.
