First, MapMyRun has a nutrition center where you can log meals, weight and water consumption, and track your caloric budget.
This fitness app tracks your eating and activity on iPhone, with its Apple Watch app providing a quick way to log meals, water and exercises, as well as notifying you with reminders and activity suggestions.
During my week wearing the Up band (and not logging many meals), the Insights never offered anything more incisive than, for example, "Studies show that exercise release feel-good chemicals in your brain".
Similarly, it won't tell you anything about what you're eating – it's up to you to log your meals and analyse them yourself.
The interactive Health Manager allows you to create and monitor your personal health calendar, log your meals, set an exercise plan and monitor your weight and medications.
To use the app, you can chose to make a "pact" to exercise, log your meals on MyFitnessPal.com or eat vegetables for a certain number of days.
Weight Watchers is another oldie-but-goodie that helps you track food intake, calories logged, associate meals and particular foods to a point system that helps you gamify your diet.
Calories are subtracted from your balance as you log your meals into the diet tracker over the course of the day.
Finally, participants already using an insulin pump are offered a second device, which could diminish compliance with regards to logging SMBG values, meals, insulin and activities.
