A smartphone app that I find quite useful is Shortwave Broadcast Schedules by Chris Smolinski at Black Cat Systems.
Chris has just announced an update which adds features like the ability to enable schedule reminders as well as keep track of your favorite broadcasts.
It’s an ideal app to use for one bag travel–indeed, you don’t even need an Internet connection to browse the listings. Admittedly, the typical smartphone screen is fairly small to display such a large amount of broadcast data, but Back Cat’s interface is designed with this in mind. I find the app easy to use and very useful while I’m on the go.
I have only used the iOS version on my iPhone. Black Cat also offers an iPad version which, I believe, would be ideal. I have not tested the Android version of the app.
