I tired to use different food logging application and also try to use Fitbit to experience as a user. I looked into: Different information propose to the user, daily usage of the health tracking device, the way that quantify the food intake, to detect possible service gaps.

I interview people who had try to keep fit or sustain their health goals to see what is their concerns and barriers.I also talked to people who have and haven't wearables to track their health. I found that the inconvenience of active food logging and the lack of nutrition information and ingredient were the main barriers that influence people from food logging.
