What's the best free way to track and analyze data about mood, sleep, exercise, and other potentially related variables?

What's the best free way to track and analyze data about mood, sleep, exercise, and other potentially related variables in my daily life?

In an effort to better understand my mental health, I would like to keep a daily log of variables like those listed, and then analyze the log for significant correlations over time. Here are the features I am looking for:

• free


• list of variables monitored can be changed flexibly


• tool will fluidly handle any periods of missed data


• any two variables can be analyzed for correlation


• other variables can be automatically calculated (say, aggregate or average of variable X over period P) and analyzed for correlation

My hope is that someone can direct me to a freeware or open source program that meets these requirements. But, if none exists (and I did try looking), I'm willing to make this thing myself.

I have a fair amount of experience programming, but very little with spreadsheets. Is spreadsheet software (Excel, OpenOffice Calc) robust enough to do this? If it can do this, can a spreadsheet be designed so that both the data entry and the analysis (at least for predefined analyses) can be accomplished quickly and easily? Or would I be better off coding something from scratch, rather than designing a spreadsheet?

Thanks for any advice!

Mood Stats is the first that comes to mind.

I'd be happy to use Excel if I were doing this project. You can do correlations between variables without too much trouble. Creating scatter plots works just fine with dates missing.

You may want to plan out carefully how you want the formulas to be laid out in the spreadsheet though, since you won't want to spend hours copying your data into a usable arrangement when it comes to analyzing it.

None of these meet your requirements, but they are along the lines of what you describe.

So yeah a spreadsheet would probably be better for you. Or maybe a hack of Joe's Goals.

Spreadsheet is the best choice. Because it will be the most flexible and you'll have all the data. There is no perfect online tool for this (that I've seen, and I've seen a lot).

I have been a member of moodjam for a while. It's an academic project (and it appears down this AM, but I used it yesterday). It's got tags for moods as well as color bars. I like it. But you can't get at your own data (they don't even have an RSS feed -- though I'm hoping to change that for 'em in the next few weeks). Plus, it would require discipline on your part to "code" all of your tag / comment entries so that you could extract the variables out later.

I've had success with similar projects using good old graph paper in paper notebooks or 3-ring binders.
