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.

Not Flawless, But Still the Greatest

Lost ability to upload to Nike+, but it seems to be because Nike wants to be exclusive, in the bad way.

I love that I can leave my phone at home and just use my watch, that I can integrate a Wahoo Tickr Run with the iSmoothRun app on my watch, and that I can use my Bluetooth headphones all at the same time. I also love that I can create custom workouts to follow as I go.

It may be my misuse, but sometimes the Tickr Run syncing to the watch makes the iSmoothRun app not show distance, which makes it basically useless until I sync with my phone again to see how far I ran. Sometimes it seems to work and sometimes it doesn’t. I’m still troubleshooting.

A Great App, Can Use  Watch 3 Alone Without iPhone

I recently started using iSmoothRun after many years using another app. My reason for switching to iSmoothRun was for the great Apple Watch only tracking of runs with my  Watch 3 with LTE.

It’s great to leave my iPhone at home and use all the robust features of the app on the Apple Watch 3. The developer is devoted to updating the app and is testing and adding a number of features for the Apple Watch only usage such as Run/Walk intervals among other features.

This is a great app with robust features and customization! A must use app for runners using the iPhone and those looking to use only the Apple Watch too.
