### 1/5 — Funktioniert nicht

*2026-06-21*

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

### 4/5 — I left a star

*2026-06-01*

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

### 5/5 — Superb app

*2026-05-09*

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.

### 3/5 — No longer works

*2025-06-13*

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.

### 4/5 — Restore inopérant

*2024-08-01*

Après contact avec le développeur, le problème de la restauration des fonctionnalités depuis un ancienne application a été corrigé rapidement. Merci 😀

### 1/5 — annoying

*2024-06-27*

constant upsell nags.
now it’s got cryptocurrency garbage.
junk

**Developer response:** As of now the app is the only way to get in a proper way notified about an upcoming expiration of an .ETH domain name. This unique functionality is designed for professional users, domain name holders. Also, if you are annoyed by an ad displayed only once a week then you can use a one time permanent purchase to turn it off forever.

### 5/5 — Great app

*2024-06-18*

an essential app

### 1/5 — Abzocke und nutzlos!

*2024-02-21*

Habe die APP mal gekauft. Jetzt wurde sie auf ein Abomodell umgestellt. Jetzt bekomme ich Werbung eingeblendet. Sowas nenne ich abzocke. Zusätzlich ist es ziemlich nutzlos, da mit dem Tools keine Admin-C oder sonstige Daten angezeigt. Kann weg….

### 5/5 — Get pro version!!

*2023-11-04*

I don’t review a lot of products.. But I thought I’d jump up here and say, I use this a lot.. glad to support Mr P.. his product has given me quite a few insights and directions.. simple interaction and detailed outputs.. Thank you again!!

### 5/5 — Excellent tool!

*2023-10-25*

Thank you very much!
