I have developed a free online address book on the Internet called EZLista (http://www.ezlista.com/). EZLista is an Internet address book where you save and access your contacts from your smartphone (mobile cell phone) or desktop anywhere you have Internet access. The site was developed with easy and security in mind. Your information is safe at EZLista. All the user/password information is encrypted at our server. They are also encrypted during transit on the Internet. EZLista requests users to confirm their email as a safe measurement to ensure that no one uses third party emails in the system.
When you are on the streets you may use your smartphone (mobile cell phone) to access your contacts. EZLista provides an easy interface that renders a mobile web site on most cellular phones in the market. All you need is an Internet browser on your phone.
EZLista is a free address book for desktop and smartphones.
