I've used Simon for several years. Quietly monitoring my own sites for uptime and speed. I've always been impressed with the stability of the product. Over the years, new features have been added and I've really taken for granted just how powerful Simon is. With v3.0 I'm very pleased to be able to fine-tune filters and monitor my sites with more granularity.

I reviewed this software, thinking it would be useful and easy to setup for several monitoring tasks. I find Simon difficult to use. The filters work counter intuitive. One of the things I tried was to check mail with apple iCloud. I could not get the map working, as it does not support TLS out of the box. I really missed a logfile of what the service is doing under the hoods. There is no (conventional) log, just an output line which does not help much when setting up new rules. Also, the help is very basic. No instructions, just a few simple examples. Left me wondering quite a few times. Waste many hours just to get some simple stuff done. I consider leaving Simon and writing custom scripts by myself, so I have full control, debugging facilities and most importantly: understand exactly what is going on. (btw, many of the services are just scripts in the Simon interface as well). too bad, tried to like it and get stuff done quickly....

Powerful and reliable, but expensive if you don't need all the features, and I found it complicated to set up initially. My main use is monitoring the pages of some internet sellers who occasionally put up stuff which sells out quickly. Simon can do this, of course, but not with the default settings, since many web pages have ads, counters and other junk that trigger false positives. So setting up an alert in Simon requires digging around in the HTML of the webpage, then adding "block filters" that check for changes in only the parts you're interested in. I feel that some kind of setup wizard could make this task a lot easier.

I'm trying to download it - both via the MacUpdate Desktop AND by downloading it via the MacUpdate download page.. but all I'm getting is "An error occurred Application error" on the download... Is there a problem with the MacUpdate download link??

I just tried the MacUpdate download link, and it worked as expected. If you can't get it to work, you could download directly via the Dejal Simon website: http://www.dejal.com/simon/

I was thinking of using this, but I managed to reliably, repeatedly, crash the software within 1 minute of using it.

Pity because I would like software with this functionality. Perhaps if they could guarantee a fix I would consider it, but I guess it won't be at this good price again!

Happened with me too, running latest Yosemite and Simon trial. Uninstalled Simon with App Cleaner, rebooted, downloaded fresh trial from website, and the crashes ended (whenever I started a test, the spinning wheel appeared and I needed for force quit the app). Still figuring out if its a good opportunity to get this!

This software is functionally very comprehensive. It can accomplish tasks that few other titles can. But, the new interface is atrocious. The goal of making everything so light, so absolute minimal contrast makes it so you have to stare at the screen, just to find out what is going on.

I really want to love this software. It performs a task we really need. But, the interface has completely killed its viability in our environment. I wish developers would stop trying to copy everything Ive does and make an interface that fits the application it is used in. This is not about making everything disappear. In fact, it is about making the important stuff appear, and not without having to be six inches from the display. Monitoring software should be good at seated position or at 5 feet. Intermapper and Lithium understood that. Your old version might have been a little busy for an interface, but functionally, it worked so much better than this one.

We were ready to purchase three licenses when we heard about the new Simon. We keep evaluating the trial, but in the end, we are not investing in this with this interface. The old systems will have to do.

I'm sorry that you don't like the new interface. The feedback I've received from existing customers has been overwhelmingly positive; people like having everything in one window, with a clean appearance.

If you have specific suggestions for improvements, I'd love to hear them, preferably in the Simon Forum:
