I am a photographer and am looking for a app that might not even be available yet. Here is what I need it to do. For each client I have a check list and model release. I'd like to keep track of these by client. Example Simons Family folder and inside checklist that I have created and possibly the emails we have sent back and forth. Then I use my iPad for them to sign the release and I save that to that folder as well. Anyone know of something like this? Or is it wishful thinking?
