I am in sales and I'm looking for an app to help me keep track of customer sales calls. I currently have a card catalog that I keep with me on sales calls with all of my customers information. As I make a sales call I record the date and what we talked about on the card so that I can refer back to it on my next visit to that customer. What I'm looking for is a app to let me do this on my htc Evo. Please any help with finding an app for this would be greatly appreciated. I'm sure that many people could use such an app. Thanks for your help.
