This app does what it says, it monitors pagespeed for you! You can set up rules to tell this service when an error occurs or if certain sections of code are slow loading (which I find really useful).
The UI has been improved since some of my previous reviews but not so much as to render its use cumbersome at all - still simple enough with minimal clicks required to get things done without having to open multiple windows/tabs etc.. It's worth giving a try out; there isn't anything about this software which doesn't make sense in terms of providing value added services over other similar products available online right now. Monitoring webpage performance across domains & subdomains- even within one domain! Setting alerts using custom parameters like "if X % load time > Y then..." etc.,etc.:.
