From the developer:
WhoDo simplifies creating new contact records. It takes care of all the fiddly details of placing specific data into the various fields. WhoDo also provides several options that can enhance the contact record. Before the contact is created, WhoDo provides an editable preview listing. This preview allows the user to fine-tune the created contact.
You may want to check out more Mac applications, such as pdf-DocPro or Pads X, which might be similar to WhoDo.
