I met the FormDesigner.pro service by chance when I had an urgent need to administer the website of the faculty where I work. Found this web form designer in a search engine among many others... Since I am new to programming and site administration, it seemed to me that this service was the most accessible for understanding and use, since it does not require any special knowledge and skills. Another advantage would be the continuous improvement of service in all directions. This includes suggestions of users! You can always get detailed explanations for any question! Great thanks for all this!

To work with the form designer to me, as a beginner, was easier than simple, an intuitive interface in this matter played an important role, as well as an attractive design. It’s good that there are such websites; have my great respect and good luck in development!!!!

Using the FormDesigner.pro, I quickly and easily solved the problem: quickly made a large number of feedback forms for the selling website. At the same time, it was necessary to make them with a set of different parameters and in a corporate graphic style. No programming, no fuss with the settings for sending application messages! All you need is 5 minutes to master the service and ... the forms are ready! Applications come instantly! They saved us a lot of money by avoiding the services of a programmer - paid subscription plans are also optional. It’s such a bless that there is such a Russian-language(!) service, flexible, simple, with lots of functions. I did not find any analogues of it in Russian internet at all!
