1. On iPad, when I clicked the link to the how it works section, the animated arrows showing the flow of checks and responses were in a layer behind the cloud images that I think are supposes to stay in the back layer. I only saw this glitch once.

2. Pricing confused me. 6 checks for $14/month. My first thought was this means you only would check my server 6 times a month, so on average it would take 2.5 days for you to notice a problem and tell me. That can't be right, so I must conclude I have no idea what a "check" is. Does it mean 6 pages or things at my site are monitored? Anyway, sine the pricing is based on checks, you should make sure no one gets confused as to what a check is.
