At the Play Store, the NIC Whois android app has just passed 1,000 downloads. This is a specialized app which helps the user find the public whois data for many domain names. Most Top Level Domains are covered including almost all two letter country code domains. Some of the new generic Top Level Domains are not covered because they use a non-standard whois interface or do not have working whois services yet.
You can download the app from the Google Play Store or from the sidebar on the left. If there is sufficient demand we could produce an IOS version for Iphones and Ipads.
