Your application can be online while your users are still having problems.

A healthy uptime check only tells you part of the story. Your users can still encounter broken flows, confusing behavior, or bugs that infrastructure monitoring never sees.

Signal 1

Application health

Your monitoring tells you whether the application is responding.

Three continuous steps keep you informed about application availability and actual user difficulties without switching between fragmented tools.
