The techy runner ,

Replaced my beloved Garmin!

I have been using a Garmin 910XT for years and love it. However, the lack of LTE capabilities meant that I had to either carry a phone while running, or be unable to communicate during long runs.

The stock fitness App on the Apple watch was insufficient for me, but this ismoothrun app on the Apple watch has the features that I need for marathon training and racing.

1) Start / pause (or lap) by pressing the crown and button on the Apple watch. (Garmin has more hardware buttons, but one hardware button feature is enough for me.)

2) Download complex interval workouts to the watch (even easier than Garmin Connect workouts)

3) Accurate GPS (as good or better than Garmin during my tests)

4) Easy export to Garmin Connect

5) Good enough battery life, more than 50% battery remaining after a 3 hour workout.

I was ok with the Garmin interval beeps and vibrations, but I do prefer the voice commands from ismoothrun.

If not for this ismoothrun app, I would have bought the new Garmin LTE watch. But with ismoothrun, the Apple watch becomes about as good as a Garmin for a marathoner, and a much more capable device overall.

The only reason I would use a Garmin now would be for ultra running training or races that require more than 5 hours of battery life. For everything else, I am using the Apple watch and that's
because ismoothrun is so good.

I rarely write reviews, but this app is so useful for me that I wanted to share my positive feedback.

Greet App

I love this app for running. It does everything I could ask for in a running app.

I started using ISmoothRun to get back into running after two decades of not running. I’ve been using it along GTN’s Couch to 5K program. I have the Nike IWatch and was looking for something useful from Nike in the couch to 5K running program and they had nothing. The ISmoothRun is awesome. Ever run I go on I can customize how many run/walk intervals I perform. The customization is endless. I really like the metronome feature. I have it set so it only plays during running sessions and stops during walks. I also use Pandora during my runs and while running it allows the music to still play in the background while the app it giving running queues and reporting on running pace.

I so happy I found this app.

I WANT to love this app!

But right now it’s just barely cutting it. The watch + iPhone setting just does NOT work. The watch app in watch only mode works as expected. Any time I try to start the watch + iPhone (from the watch) it just displays no info on the watch and the iPhone app sits at the start run screen. Don’t cut and paste your standard check your settings faq either. I’ve checked them all. Smashrun... I love your website but you might want to consider a “ymmv” statement when recommending this app right now.

Update: I got the watch and iPhone app working together by starting the outside runs from the phone NOT the watch as shown in the faq. However, treadmill plus this app = fail. It constantly repeats stats, goes to auto pause when auto pause is disabled and doesn’t record the pace or distance correctly on a treadmill. The watch is recording the correct info and can be seen in the watch records. It’s the app.. right now it’s working ok for outside runs and that’s it. I’ll still use it over Nike’s nightmare though. It sad that the Apple Watch is such a running tool failure.
