I don't quite see the problem this app is solving (beyond initial curiosity). Some wild ideas, not necessarily good ones: * Everybody knows enough sleep is a good thing, but not everybody has a productivity chart to make its importance visceral. * Provide early warning signs to rest before you get migraine. Common triggers are stress, hunger, fatigue, hormone levels (medication), indoor air quality and lighting. A common early warning sign is an unusual appetite. The facts are known, but their importance varies and not everybody is sufficiently self-aware. * Automatic goal tracking for Beeminder, because that increases the chance you achieve your goals. * Prevent procrastination: Is it possible to infer mood from your data, e.g. movement patterns, after some initial training? (The food industry can measure feelings amazingly well in their food design labs.) I know I'm much more likely to procrastinate when I'm low on energy. Right now, I'm trying to notice that earlier and take a break or fix the underlying problem.
