Most Fitbits can receive notifications from your smartphone, including calls, texts, and calendar alerts. In this way, FitBit will become part your life more tightly. The notifications can come from Google Hangouts, regular text messages, or messages on FaceBook Messenger or Skype.
Another Fitbit app option is third-party “MyFitnessPal”. MyFitnessPal has a much richer selection and a more in-depth app focused on diet monitoring. If you want to get all the benefits of a huge food-tracking system, MyFitnessPal will be a good choice.
