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.

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.

Great Solver with convinient interface Great solver with convenient interface

Great for optimizations In overall, we are satisfied with the product. We had few frictions due to: - license validation in big infrastructures (with proxies,...) - Instability of the plugin that gets desactivated in Excel - After calculations, the sheets get blinkering (switch betwen sheets, mouse cursor changing state,...) so we have to wait 1-3 seconds before the application stabilizes with some bigger excel files

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.
