Overview
If you want to design apps for smart watches, it’s important to know that different platforms have vastly different capabilities. Apple Watch and Android Wear, for instance, serve primarily as smartphone extensions with fast CPUs, bright displays, and relatively short battery life. Pebble’s watches improve on this with better battery life and screens that work outdoors. Garmin watches take battery life and durability a step further.
It’s said that if you know how to build a boat, you can build things that will stand up to any environment this planet can throw at you. The "boatbuilders" at Garmin have created watches for long-term use in punishing, sometimes extreme conditions (such as a 24-hour ultra marathon).
In this report, author Brian Jepson takes you on a hands-on tour of Garmin and its Connect IQ SDK. Garmin goes furthest in prioritizing run time and resilience over raw processing power, but as you’ll discover, the watch does not sacrifice the functionality you need to develop first-class fitness- and health-related applications. This report explores both the advantages and constraints of working with Connect IQ.
- Explore Garmin’s ability to collect data from users and return timely results to them
- Start developing for Connect IQ by using templates for four kinds of apps
- Work with example projects in Connect IQ, including ways to read data from an ANT+ sensor
- Get developer resources for building wearable apps that do more with less

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.Addison B.
