Hulk Contact Form Builder

Sadly my experience was poor as I spent an entire day building an extensive form while hitting save regularly, but when I went to get it back it had not saved at all. The Hulk customer support was excellent but they could not work out what went wrong as their own test saved perfectly. I assume from all the positive reviews that this is an excellent app but I won't be using it as I am not going to spend more time on an app which let me down the first time I used it.
