Simply the best Frontine's products are simply the best analytics tools available for spreadsheets. And if spreadsheets aren't your modeling platform of choice, their SDK gives you access to everything they've got to use in any way you want. They have been the leading innovator in this space for decades and their customer support is second to none.

I use the product regularly because I find the Excel-based transparency and convenience a nice complement to working in Matlab. I use the product regularly because I believe it is best in class. I think some of the upgrades are too expensive but I have no issue with the quality of the product. I find the frequent requests to confirm the license annoying. I travel internationally and have been locked out of the product when I was having internet connectivity issues. There has to be a moratorium on this (e.g. allow a week, a month before disabling the application). Also, Frontline has been the most difficult vendor for my IT folks to work with when it comes to using my license on multiple machines that only I operate. Again, there must be an easier way. Finally, I did try the consulting service and my experience was positive - worth the money.

Excellent support Frontline Systems has provided excellent support whenever I have had a problem. I recommend them and their products highly.

Excel can become unstable Excel can become unstable. Many times i have to remove the Frontline add-in from excel to improve stability. I use the add-in about 2 or 3 days a month so this is not something that is all the big a deal. If i leave it installed i have more issues with excel freezing up or stalling and generally i dump the add-in. The installation and annual update process was greatly improved.

Good app, but untrusted by Google. I really enjoy using the free version for simple arithmetic solving. It has a good interface that I prefer over some open-source versions (I am using this in Google Sheets). However, I wanted to let you know that Google flagged this extension as being suspicious and was not trusted. I will keep the app, but I highly suggest you work with Google to get on their trusted vendor list.
