PE logging tool

Hi there all. I was wondering what everybody is using as a tool to log their measurements and improvements?
I myself use Google Spreadsheet, but I was wondering if I couldn’t make a custom application. Something along the lines of that piece of software (Gain Master PE Software Release!) made Iguana some years back, but online and not running on anything Windows. I just wondered if there was any interest from the community.

PS: if there is another tool which already does this or you just love, please post it, no need do stuff twice :)

I use/do a combination of things. First, I log ever workout in a spreadsheet. That is the date, the total duration of the work out, number of reps of each exercise et cetera. I also log any notes about that session, if I felt sore before or after, if something of note happened et cetera. I have another sheet in the spreadsheet where I track my measurements. Along with that I also track my measurements in the stats tool on this site, which is something I am surprised more guys don’t do. Lastly, I like to visualize my progress. So I go to the site

http://www.thevisualiser.net/ and create a side-by-side of where my dick is now versus when I started. It also does stuff like shows relative volume stats, which is nice.

Yea, also used The Visualiser, it’s nice to actually see the gains before and after, kinda.
