One of the key enablers to substantial growth in the Internet of Things marketplace will be the progressive emergence of integrated ecosystems of devices and software systems that interact in meaningful ways.  I currently use the FitBit One device to track the steps I take each day and record the food I eat in the MyFitnessPal iPhone app.

As I was browsing the MyFitnessPal website recently, I noticed a growing number of partner applications that interact with MyFitnessPal in some way.  Upon further inspection this morning, I counted 51 apps that interact with MyFitness Pal.  The website lists four devices that are integrated for weight management:

1. Fitbit Aria Wi-Fi Smart Scale
2. Withings Wi-Fi Scale
3. iHealth Wireless Scales
4. Wahoo Balance Scale

Seven devices are listed for activity monitoring

1. BodyMedia FIT
2. Fitbit Tracker
3. Striiv Play Smart Pedometer
4. Fitbug Air Tracker
5. Jawbone UP
6. Lumo Back Posture Sensor
7. Withings Pulse

I am currently very impressed with the useful integration between the FitBit tracker and the MyFitnessPal app that I use daily.  If the other apps and devices are as well integrated, this fairly simple, but growing ecosystem has great potential.
