I absolutely love the idea. I have a local business and I'm able to get my volunteers sign in via my iPad. My business and community looks so professional and I'm satisfied with the usage. I'm able to customize the sign-up for exactly to the theme of my business. I've been searching for an app like this and am extremely delighted I've found one.
For those of you who are using FreshMail - this app is highly recommended! It helps to collect email addresses anywhere :) Beautiful templates, and the app itself.
Seems to be good for what it claims. I love this app, makes it easy to gather emails for my beauty salon clients.
