You can use all of the smart phones, ipads, itouch, etc to review your collection with Collector's Assisitant by saving your you collection as a .pdf.

The Collector's Assiatant is working hard on a new app for the ipad which will allow you to actually enter data , sort, etc. I just happened to speak to the code writer today about it.

In the meantime, you can review your chips to know what you have just fine as a pdf. The website to get the program: www.HappyChipper.com
