Good but won't post to Facebook!

I really like this interval app. I've used it to, er, restart my running habit just about every year after I inevitably fall off the wagon. I like the simplicity of it, and the directness of the spoken instructions during a run - nothing gimmicky, just a direction. My only criticism is that it never allows me to post to Facebook! I have uninstalled and reinstalled the app multiple times, and it still won't post! I don't know what's wrong, but it has been a problem since I first downloaded the app in 2012...

Still Great, Despite Shortcomings in Customization

Very clean & intuitive. Building new workouts is quick & easy.
I wish I could custom label the steps in the workouts, though. Most timer apps have this feature, allowing you to build more than just running routines. Still, I use this app over the dozen or so others I've tried because it is otherwise perfect. 👍🏽

Great but No Apple Watch App?

I LOVE this app! Will you be coming up with the Apple Watch version of this app soon?
