This app does require some setup time, but it – Device Magic: Get Mobile Forms Review

I switched from a cumbersome paper-and-pen form to a form developed with Device Magic’s form development software, used on my iPhone. You do need to set up an account in order to use Device Magic's online development software but the account is free for use with one device and you can receive the form in your email, GoogleDocs, etc. Some options are not free, but these two are, and are the ones I need. The form is entirely setup "from scratch" as it's entirely customized to your needs (there are no "stock" forms), but it was easy to do with their new online development software. The time spent was well worth it! You can create fields for a customer signature, GPS location, a photo of the customer's equipment... all fields can be made optional or required or dependent on other answers... Great level of customization! The Device Magic form is much more consistent than our old method and it’s impossible to accidentally omit critical information on the form. And it never fails to impress clients, either; they seem to especially like the signature field feature. Their expressions are usually priceless when I ask them to "sign" the form after they read my disclaimer (also in the form). During development of the form I had some questions and needed assistance. I contacted Device Magic on several occasions and I’m very happy with the support I received from them. The response time was very good and the level of knowledge was excellent! I can happily and highly recommend Device Magic to anyone who uses forms “in the field”. - Dave Holmes, owner of Affordable Computer Service
