Looks like this app hasn’t been updated in awhile and that’s a real shame. It WAS the best PSK app for iPhone/iPad. Now, it just flat out doesn’t work on recent versions of iOS. I’ve had the app for years, but haven’t used it in awhile. Much to my disappointment, I opened it up today and it just doesn’t work. Just compared to the other PSK app, it appears this one needs to be updated to allow it to ask for permission to use the microphone (for audio input). This app doesn’t have a setting for it, the competing app (which frankly isn’t as good - but it works), does have that setting. Let’s hope the developer updates this app and I’ll be happy to give it a high rating. 73, KI4ASK

Does not show anything on the waterfall and does not decode any signals when using a direct cable connection to the headset jack. Other ham radio apps which support the line input work fine, so this is a defect in this app. Please fix!

So far, this app is doing what I need it to do: get me on the air with PSK31. I use a small speaker next to my iPad to receive the signals, and use a hand mic and VOX for transmitting. Only issue I have isn’t really with the app itself: I also log on my iPad, so I can’t have my log open AND use the app. I guess I need to hand log during PSK31 and then transfer into my logging program later.

This app has an audio TX issue with direct connect to certain interfaces. The RX works fine. I initially thought it was the interface but have confirmed other apps work just fine. Hoping the author corrects this quickly as this is an important issue for many users.
