WiFi drop out

Generally works ok, but if searching and entering a number stations, wifi connection drops out and has to be reset. Radio is Roberts 94i

This bug needs to be sorted as this is the only app that you can get on Apple that will do this job

Works Great

It’s hard to write because it’s only occasionally I need to go in. The radio is delivering to distributed audio system in my house. Just once in a while it goes to sleep and the app is needed to wake it.

Works fine

This is the only app that will control your Numan Hi-Fi. Nothing to write home about, but works perfectly and never crashes.
