Yes - 100% safe. It was created for free by a long-time member of this forum (Matthew). He used to be a very active poster a few years ago but we don't see him too often here now. Again, 100% safe.
 
Ok greeat thanks for the info, I was worried it was illegal ... I do not know how it works really but it seems it get access to your ecas and advises you of any change instatus/update
 
It's a fantastic tool. I used it when my husband was applying for PR and it's much better than always having to check the CIC web site yourself.
 
It is safe. However, it doesn't fully works for citizenship applications. The software will alert you when your e-CAS is live, but it won't give you updates on changes under the "In Process" link.

As mentioned before, it does work great for PR applications.
