Works with Sangean radio

Downloaded this app to replace the iSangean app which stopped working after the iOS9 update. UNDOK works ok on the iPad to control the Sangean radio. It is a little slow to connect sometimes and the browser pane has frozen a couple of times hence 4 out of 5 rating. Overall I'm happy with it.

Alternative to sangeans

I am very pleased with this app,it is an alternative to sangeans. Since the update it very responsive and a joy to use. Thank you. If you are like me and have sangeans app 1.2.3 on iOS 9 you will find it does not work but UNDOK DOES. Hope this helps.

Crashes on launch

There doesn't seem much point in adding more features when the app crashes 95% of the time on launch. It occurs on both iPhones an iPads and has done so for some months now. No point installing it until there is a release addressing the problem. That said it would be ideal if it worked.
