Create a simple or advanced form that lets users contact you via your app
Not only that, you can also include quick connect buttons like the ones shown below. For example click the phone icon and the dialer will open, the email icon starts the clients mail add etc...
Ours FreeForms widget also has a built in autoreponder and a post url feature for sending the data to an external database.
Also, see the coupon widget which allows you to offer a reward (digital coupon) when someone completes a simple form. Background colors can be changed on all forms as well.
