1. Kitlog Pro to log the construction with photos and expenses. It also allows you to convert the log to a website at the press of a button and when the build is complete you can create a PDF file of the whole log at the press of a button.
2. I use an Excel spreadseet to log the day to day hours as I don't want to record everything in Kitlog - it is dead easy to use and I add comments to note what I have done. Check it out on my website and the link is at the bottom of the construction hours on the homepage.
I use www.expercraft.com. It's completely web based so you can work on it anywhere with a mac or PC. It has its limitations but it's free and works relatively well.
