Horrid support, does not work with Biosport (though it says it does) – iSmoothRun Review

Purchased a SMS Audio Biosport headphone and ismoothrun was the only app stated to work with it. Could not get it to work (lack of clear instruction) and SMS audio did not respond to my email enquiry. Since there is not trial version of this app, you must buy it to see if it works. (it even says so on the website) As mentioned I could not get it to work, but there were other negatives: 1. Seems like it has no treadmill support 2. No iPad version (for treadmill use) The only thing the app would do is cause the volume to pulsate. Would like my money back. I did contact ismoothrun and 8 days later this was their reply verbatim: "Sorry for the late answer. The app should have permission to use the microphone and the above procedure should work."
