Funktioniert nicht

Zu genau der einen Domain, für dich ich Infos haben wollte, konnte nichts gefunden werden.

I left a star

I left a star hoping the developer(s) will add some more features… Basically I’m holding it hostage until then.

Superb app

This app is superb. It conveniently and efficiently retrieves the data available on a domain, and displays it cleanly. They added a new feature on the premium level, where you can look at the history of the domain.

No longer works

I used this app to track my domain purchases and now it no longer works due to updated Whois server being retired. Is there going to be an update for this?

The history still works which is mostly what I use to see the history on a domain I’m wanting to purchase. I’m happy this still works.
