Best Form Tool Around.
I am a consultant and use Titan/FormTitan with almost every client of mine. It is extremely versatile and can do almost anything needed. It has so many use cases for external forms as well as forms used by individual users and teams making it such a valuable tool. Their support is incredible. There is some learning curve and their help is almost immediate and so comprehensive.
Having experience with many other form tools over the years, there is no comparison!
