The biggest thing that sets this tracking app apart from the rest is that it allows you to completely customize what you track. Many of the other apps I tried often had a limited set of categories that I was interested in tracking, and their criteria or scales were off. Take "mood," for example: most apps put mood on a scale from "happy" to "depressed," but mood (at least my mood) is more complex than that (sometimes I feel "aloof" or "anxious"). With this app, I can set the values for my mood with criteria that match my idiosyncrasies. I also like that I can export to CSV (with no upgrade or pro account necessary), and I can then customize how my data is visualized. With this app, you own your data.
I would give it five stars just for its feature set, but it has crashed a few times, usually when I do something like trying to slide a screen that doesn't slide. Also, I really don't like the lo-fi faux notebook rings on the main screen, though the graph paper background is apt. Overall, these are very minor issues.
I highly recommend this app.
