I use Numbers and made a few spreadsheets. It's apple's version of Excel. There is a great thread about using excel that should give you some ideas of how useful it can be. For some reason the spreadsheets take up a ton of room if you save each individual one on your phone. I created two templates and email myself a copy of everything I estimate. I have a folder in my email that I save the spreadsheets too.
