The best there is

This app excels in all the ways you’d expect. Easy to setup, manage and use. Nice multi-select is a treat to have, as are the swipe conveniences. Getting quick looks at the pnp graphs work really quickly for services as well.
And no, the author never claimed to have push notifications...and why would he want to? It would cost plenty for all the notifications people would use it for. Use pushover with your monitoring servers, as already mentioned. Penalizing for a feature that isn’t desired or promised is lame

Nagios XI

Just installed our own Cent0s VM running Nagios XI and monitors about 75 different hosts. This does a great job at letting me do both instances (internal IP and external) that way I don’t use Rackspace cloud bandwidth. It works perfectly and this is required by IT admins!

Very good at what it does, but lacking a couple key features.

This app is GREAT for checking status, but it would benefit greatly from having alerting features.

I bought this thinking it would alert me when a service or host goes critical, but it does not do that. I still have to rely on email notifications.

It would also be handy to have the ability to look at the alert history. You can do that looking at the graphs on a per service basis, but not holistically.

Like I said before, what this app does it does very well, but to it is missing a couple key features to make this the perfect Nagios app.
