This form app is amongst the best I've used and has saved me a ton of money by not having to use Typeform. The app's features speak for themselves, but my rating is entirely based on Meydjer's support -- it is simply top notch. He not only promptly squashes any bugs, but he's open to implementing new features. I hope to have the ability to add a signature field soon!
Lastform is a great addition to Gravity forms, and it really does make the forms a LOT more appealing. Great stuff! Also, when I had a problem with my form (due to a conflict with a plugin I had installed), Maydjer helped me quickly and thoroughly to solve the problem. Thanks a lot! I can definitely recommend Lastform :-)
