Very Good App, until lately

This app started having issues this morning with broadcasts breaking up. Then tonight I opened it up again & none of the play information was current, also the drop down menu was missing the “playlist” link. I deleted & reinstalled but continue to have same problems.

Terrible app, plagued with ads

This is among the worst apps I have ever used. I love KCSM and am a supporter. But the KCSM app ads are pervasive and cannot be dismissed. I tried the Safari browser on iOS and it’s even worse. There, the ads actually stop music playback until one acknowledges the ad. That’s totally unacceptable. For now, the only ways I know to listen are: 1) using a radio (such as in my car), and 2) through a computer browser with an ad blocker installed. From reading through many older reviews of the app, it has never been very good. This is in contrast to many other radio station apps that work flawlessly and are designed well. Why can’t KCSM get this right after so many years?

App now works with iPad digital output!

A few months ago I gave this app. one star because of the problem explained below. Accidentally opened the app. today and they’ve apparently got iPad digital output to DAC via CCC fixed. KCSM, thanks for listening!

I LOVE KCSM and have supported it for years, but I’m disappointed in this app.

When you plug a headphone amp/dac into iPad via the Apple Camera Connection Cable, the app continues to output audio via the analog headphone jack instead of switching to the digital out. Other jazz station apps act correctly, and the WBGO app is a great example. Plug in your amp/dac via the ACCC and viola! Pure digital bliss fills your headphones.
