Now that the Series 2 has been out since October, and it's now the end of January, I wanted to give an update on my running with the Series 2. I have chatted with many users on here and heard your thoughts as well. Please chime in and give your experiences as well. As a disclaimer, I run between 20 and 30 miles a week, and try to incorporate some swimming and biking in as well. I'm training for a sprint triathlon in May. I run on the road over known distances, and also on the trails in and around Portland, Oregon. I also occasionally use an Garmin 735XT triathlon watch. DISTANCE The Apple Watch is accurate when using the built in app or the Nike+ app as far as distance in concerned. I find that many other apps are consistently off by a few percentage points and many apps do no correction and are horribly off, especially the hiking apps. I have tested the apps that use the onboard GPS, including, Nike, Pear, RunKeeper, Trails, and Viewranger. PAIRED WITH PHONE Over the last few months, many of the apps now give you the option to use the phones GPS (including barometric altimeter) or just the watch. Runkeeper does this as well as Trails. Trails has no Pause AT ALL on the watch which is crazy. Runkeeper has a nice interface and gives you the option to choose between 3 sports ON THE WATCH. Why not all the options that are on the app? Plus no Auto-Pause on the watch. Nike+ will only use the GPS on the watch if started from the watch. If you start from the app, it'll use the watch as a second screen. Unfortunately, it'll save two activity events at the end. Still work needed to be done by Nike there. Sportstracker is a nice app that works only with the phone, but is buggy on the Watch. No one app seems to work perfectly. Activity ++ does not use GPS, ViewRanger is better but is geared towards hiking, as are GPS Tracks, GAIA, and others. ISmoothRun and Runmeter haven't updated their apps with anything meaningful in quite some time. Nothing new from Strava yet. ON THE TRAIL Yesterday, I ran a trail in Forest Park in Portland; heavily wooded but a very popular trail nevertheless, in the city. I pre mapped the route on Strava to estimate the distance. 4.7 miles. I ran with the Nike app and my Garmin 735. The AW2 recorded 4.8 miles compared to 4.4 with my Garmin. I notice the Garmin seems to struggle a bit in the woods. And yes, GLONASS and GPS are turned on. Anyway, they are usually pretty close to each other on the open road. CURRENT PACE, ETC. I believe that the one flaw the AW2 has is the ability to display a consistent current pace. Through any of the apps I've used, the current pace is basically unusable. Also in the results at the end, they don't really make sense. Everything AVERAGES out ok, but to use it during a run doesn't work. I'm guessing this is a hardware flaw. APPS The Workout app gives you the basic amount of detail which is too minimal for ME. The Nike app is hot garbage. Syncing is abysmal and the app is a gateway to sync with other apps at best. I have personally figured a way to sync consistently, but if you want to get your data out through something like RunGap to Strava or Garmin, you MIGHT have to wait for HOURS. Oh well. While RUNNING, The Nike App works well. The SportsTracker app is the most well designed app Ive seen or used. If only it worked better on the watch! Obviously you can export your data from the Native Apple app minus the maps by using RunGap. You can also do this for Nike and RunKeeper as well. RunKeeper's data, once uploaded to Strava is all over the place. I've read several blogs about this and don't understand why. If you care about cadence data, using Nike will not help you. No steps are recorded in the Nike app when running. So if you export your data to Garmin, your cadence will not be recorded. Small minor detail, but good to know nevertheless. Garmin's app is feature packed and a good place to store your runs as they have nice graphs and historical data. Strava is the king of social running and can auto receive runs from Garmin. So my current workflow is typically to run with Nike+, then upload to Garmin/Strava/Sportstracker via the RunGap app. Works fairly well. MOST OF THE TIME. The Nike App gives great voice feedback. Runkeeper is a barely noticeable haptic. HR I think the heart rate monitoring is actually pretty consistent depending on the app. Ive seen a few apps where the monitoring didn't start right away or stopped in the middle of the run. When it's running, it's very much on par with the Garmin. I had a Wahoo Tickr X for a while and don't wear it at all anymore. BATTERY LIFE Not really an issue as long as it's charged sufficiently. That's partly why I keep the Garmin around. In case I have a run and have forgotten to charge my watch. But that's extremely rare. I also try to reboot my watch once a week. It's a computer after all and I think it helps the watch be less glitchy. Works for me. By using this method, I've only had my watch fail to record properly twice using the Nike app. Once I started rebooting weekly, that went away. NEW FEATURES? I'd love to just use the native Apple app. Give me the ability to export via a share sheet or RunGap and most of my complaints go away. It has many of the features that other apps just don't have, like the ability to pause by pressing the two side buttons. In the Activity app, give us dome graphs and more details, even under an advanced tab. Let us re-name activities. Nike needs to allow for an option to use the phone or watch and to make the app understand the difference. Elevation data would be nice to see on the watch if using the phone since it has the barometric altimeter. Strava? Well we just have to continue to wait. Overall, I continue to use the Nike app (55 times since it came out) and the Garmin too on the weekends, usually for comparison purposes. I'm very picky so that doesn't help, but overall pretty satisfied.
