Hi there =)
So regarding the first question about Iphone app I have a lot of request for that platform but I don't have resources to invest on Iphone platform right now. I will try in the future to also port this and other applications to there.
You can also move to the dark side of the force, Android
Regarding the IP adress, this application can monitor any IP, URL or DNS (for example
www.MyHome.com), it don't have to be the Router IP. Just give the widget the input and it try to reach it through Ping or port-scann. You just have to make sure that the IP is exposed to the internet.
If you have any sugestions or malfunctions just say it.
Hope the application helps you as it helps me =)
Greetings.
