What I mean is that most apps / wearable tech seem to require lots of manual data input (in my case, MyFitnessPal, Runkeeper, etc.)--although some of this has gotten better with say, tracking steps. Regardless, I feel like a lot of my life is currently data input.
Whatever future app development ideas come to fruition would benefit heavily from having a high level of simplicity and automation on the side of the user while still doing some difficult data crunching that is VALUE added.
I think this is one of the reasons Mint.com is so popular. It requires very little input from the user and quickly generates a LOT of very useful information.
Imagine how useful it would be if my nutrition information, blood pressure, glucose levels, etc. were all recorded for me automatically. Then I wouldn't have to think about them everyday, I could just examine them when I'm curious.
