Hey HN! My friend augustflanagan and I both had a need for some really simple cron monitoring. A way to monitor our critical jobs without configuring Nagios first. We wanted a simple SAAS monitoring solution that we could trust to alert us right away when a job isn't running on schedule. 

We mentioned this to a couple of friends who said they needed the same simple monitoring. Having people tell you they need something is a great motivator, so we built cronitor in a couple of weekends and are putting it out there. We'd love feedback and suggestions on how to make it better. Thanks!
