Every Feature You Need, and Truly Free

This app and the UI are very well thought-out and executed. I can’t think of a feature that’s missing, it fills a major gap left by other bloated, half-cocked, subscription-based apps. Well done! If Nagios is your monitoring agent and you are an iOS user, I couldn’t recommended this app more.
