Changes

Garmin's Connect IQ allows for the creation of apps to run on Garmin's [[Best Running Watch| running watches]] in much the same way you can run apps on Android or iOSand iPhone. This has the potential to make makes the new newer Garmin running watches as revolutionary as the first iPhone. Before Apple introduced the iPhone, a smart phone was largely limited to the functionality that was provided by the manufacturer. Now there is a huge portfolio of applications that allow the iPhone to be used in new and novel ways. I believe So far, we will see 've seen a huge explosion in the number of apps available for Garmin watches, and this has dramatically improved the functionality, especially in the lower end watches like the [[GarminVivoactive]] that were a little crippled out of the box. It's Connect IQ change not reached the point where seeing with smart phones, where they are primarily a platform for the apps with the way we view phone functionality as a secondary feature, but it's not inconceivable that this might happen to running watches. =App Types=The Connect IQ allows platform provides for four different types of app; watch faces, data fields, apps, and widgets.* '''Watch Faces'''. Each watch face can customize the default display, providing far richer information. Some of the watch faces available are simply prettier, while others cram on fast amounts of data, but my favorite watch faces provide insight into my recent training.* '''Data Fields'''. These data fields are displayed during a workout, and are probably the developer most valuable for many runners. In addition to create the obvious functionality of displaying data, a data field can also record new applications that utilize information into the FIT file, and can be customized by the runner using either the mobile app or the PC software. While there is a huge variety in the various data fields available, I would group them into these broad categories:** '''Visual Data'''. A data field can be used to display data graphically, such as a graph of heart rate, or to color code the current value to provide faster feedback.** '''Calculated values'''. A data field can displaya new type of data such as [[Relative Running Economy]]. ** '''Sensor integration'''. A number of [[Running Sensors]] have used a data field to integrate with the Garman Connect IQ watches. For instance, sensors[[Stryd]] uses a data field to display their [[Running Power Meters| estimate of running power]] as well as recording extra metrics such as [[Ground Contact Time]].** '''Single Field Display'''. There are several really useful data fields that are used as a single Field, taking over the entire watch face and ANT+ connectivitydisplaying far more data than is possible by default. Some This is particularly useful in some of the things lower end watches like the [[Garmin Vivoactive]] that should be possible include:only support three fields out of the box. With the right data field, it can now support five data fields, plus time and battery level.* Connect '''Watch Apps'''. The watch apps are intended to new devices function as a workout type, or similar "full function" software. They handle all button presses, data recording, and display. I think that apps might have the greatest long-term potential, but they're also the toughest to develop. Most of the watch apps I've tried have been underwhelming. (Sometimes Garmin refers to watch apps as "applications", or even just "Apps" which creates a bit of ambiguity and confusion.)* '''Widgets'''. A widget is accessed by scrolling up and down from the watch face, and they are intended to be much lighter weight than a full app. There are intended to provide additional informationat a glance, and they can't record data or integrate with external sensors. =Favorite Watch Faces=There are a few watch faces that I've come to really love. The first two provide a graphical display of your activity over the last week. For instanceThis allows you to see how your training is progressing at a glance, there and can provide some additional inspiration to keep you moving.{| class="wikitable" style="margin-left: auto; margin-right: auto; border: none;"|- valign="top"|[[File:Actiface 2.png|center|thumb|200x200px|This is "ActiFace", my favorite watch face for a long time, with a company nice graph of steps over the last week, plus lots of other data.]]|[[File:GearMin 2.png| center |thumb|200x200px |A rival to ActiFace is the "MinGear" watch face that improves on some aspects.

In the early days of Connect IQ to integrate there were a number of watch apps created because that was the only way of recording additional data. With later releases of Connect IQ, a data field can record additional data, so these apps are no longer needed. You can see this with [[Stryd]], which was initially released as an app, but now you're better off with a device the Stryd data field. To me, the watch app that embodies the potential of this approach is "dwMap" by mappicus. This watch pants the functionality of following preloaded course is to measure blood lactatethe more basic watches like the [[Garmin Vivoactive]]. [[File:dwmap.jpg|center|thumb|200px|The dwMap watch app on the Vivoactive.]]=Favorite Widgets=* Existing devices So far, widgets have been even less impressive than watch apps. There are some limitations on what data the widgets can access, which may be used in new wayswhy they're not as innovative as I'd have hoped. For instance, a widget can't get a list of all of your activities to evaluate your training history. Let me know if you've found a running watch does not provide speed from a Footpodwidget that you'd recommend. [[File:SunAndMoon.png|center|thumb|200px|This app shows sunrise and sunset times, which is nice, this could be added with but the data is available on the Connect IQwatch faces I use. A clever developer could go further ]]=Connect IQ Limitations=Garmin are continuing to actively develop Connect IQ and implement expand its capabilities. There are a more sophisticated algorithm few limitations that have annoyed me and I feel are worth mentioning.* So far, the Garmin watches can only have two data fields active for adaptive calibration any given workout type. That makes sense, as you don't want the functionality to slow down or impair the functionality of the Footpodwatch, but two is rather a low number.* Data There's no access from a data field to the data from Garmin's [[Running Dynamics]], which I think would be a valuable source of data for calculated values.* You can be combined 't access [[Heart Rate Variability]] data from a data field.* Watch Apps operate in a low-power mode that restricts their functionality and graphed, for instance using heart refresh rate .=Connect IQ and distance to calculate Relative Running Economy.Suunto Apps=
