About the only way I can track any kind of diet or exercise regimen is if I track the stats as well. As long as there is some kind of visible progress, I can keep my motivation up. The trick is in finding a way to do this that doesn’t get in the way, and allows maximum flexibility for playing with the data later.
I always write it first in a notebook, out of habit and paranoia. I used to use a spreadsheet until it having a smart phone and an iPad meant I never had the latest version with me.
I looked around at other apps out there, and frankly, they’re all toys. Weightloss is an emotional topic, and unfortunately the associated software is designed to appeal to emotions. I want facts, and the ability to twist those facts into something I can call good news. I don’t need candy-colored fancy graphs and whatnot. I also want to calculate the lbs of fat and lean mass from percentages my scale gives me, and heartbeats per mile on my runs.
Turns out there’s a DataGlass app for iOS that talks to my database server (if you have a blog, you probably have one) and lets me enter and view data. I made a few views to do totals and weekly averages. The app even does basic graphs. Sweet!
