Still not iWatch user Friendly 🙁

Rand Ian

Read some reviews and ended up buying this app to enable recording HR from my iWatch. Spent quite a bit of time trying to figure out the settings, but still to no avail. Finally reached out to their support - I believe, the session should be started from the iWatch and not from iPhone in order to record HR. The app doesn’t not have any start /stop /resume/end screen - it is supposed to come up by force. After multiple times got it start a session but was not able to end the session, had to turn off the iWatch in order to end the session.
Reached out to the App support with making the app more easy to use.

I was assured that they are working on those enhancements and will be included in their next update. I hope they release the update soon, until then my two star stands.

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.

Great App!


My coach first recommended iSmoothRun to me because it integrates well with Training Peaks. I have continued using it because I love the ability to program my runs, and the accelerometer when the GPS doesn’t have signal (in tunnels, sometimes really deep forest trails with lots of cliffs, skyscrapers, etc.). I enjoy the data I can see as well. Programming shoes and keeping track of the miles is also invaluable to me. Keep working out the bugs. Thanks for the great app!
