One of the best ways to get more activity on your mobile app is to get your customers interacting, through feedback, input and more. You could do this by adding a Form Module (feature) in your app. Use wufoo.com to create your survey form and then click insert in the Machine.
To do that, click on the “Make or Choose a Form” button and a new window will appear. From this window, login to your existing Wufoo account and just click “Insert” on a form which you have previously created. Or, create a new form, and once it’s completed, click “Insert”. If you don’t have a Wufoo account, you can quickly create a free one in the Machine, and then follow the above steps. Once you have inserted your form into The Machine, remember to click on Save.
