The new voices are horrible!

I have been a fan and ardent supporter of iSmoothRun for at least 6 years! It’s been a partner on my journey from non-runner to 3x weekly enthusiast!

The thing that has kept me here at the small independently developed app, instead of jumping out to the popular platforms was the fantastically recorded, unobtrusive, human voices of iSmoothRun. That voice piped up only with enough information to let me know how I’m doing without distracting me from the run and the music.

The new robotic Siri voices just don’t cut it. They’re unintelligible and quiet, requiring music cut instead of duck, and they’re just distracting and annoying.

Please, please go back to those lovely voices from previous times! Or at least let the user choose those over others. And if the recording does not exist for a message cut in with a Siri imitation if you have to!

Simply the best

Accurate tracking and the best app for connecting to sensors and displays - the Apple Watch stand alone app works great. Track your runs (including advanced intervals), hikes and rides in iSmoothRun and share to RunKeeper, Strava and other social platforms. The developers continue to update and refine iSmoothRun - cannot recommend the app enough.

Apple Watch stand-alone

Been using the app for years but have been hanging out for the stand-alone watch function.
Native Apple Watch app - works great but can’t export.
Strava Watch app - exports to Strava but is awfully inaccurate.
iSmoothRun - finally an app that shows if you have gps lock on the Watch plus it exports!
Love your work!
