I love the idea of collecting personal data through a few timed surveys. Easy to use. But right now its just a shade of what the app could be. You should be able to generate reports cross-referencing the data with if-than radio buttons. What if I want to know if I drink coffee at different times at work when I skip lunch? Or if playing video games too late in the day affects my sleep? Or if I work more efficiently when I am exercising regularly? You could get all these results with a more dynamic report generator. Right now it just gives you information without it being very useful.
Also please include a "time" option in the survey editing menu that the app recognizes, so we can have questions like "when did you last drink coffee" or whatever.
