Fitbit has rolled an updated version of its iOS app for the iPhone 5s.
Users can now monitor steps, distance covered, and calories burned. Fitbit also offers more than these essential features, with devices like the Fitbit Flex wristband, or the Fitbit Force, which allows you to track the basics, along with sleep, and stairs climbed, and displays details on the digital screen (like a watch).
Having said that, the app is still the core of the Fitbit hardware experience, because it presents a dashboard for every metric, as well as a log that records nutritional intake so you'll be informed of your general health over a period of time.
To complement the launch of the M7 motion co-processor in the iPhone 5s, Fitbit is offering primary tracking from the mobile device itself, which the Fitbit team is working on to enhance.
