The app is promising a lot. But in reality it does not clearly decode, the waterfall is almost complete black, even ongoing qso‘s are almost not appearing. There is no good squelch and so the app keeps decoding thousands...Nice try, but not working.

I was really surprised how good it works on my iPhone 5s.You can read messages in PSK31 (even if you use speaker of TRX and microphone of iPhone only). Tuning to different stations is not really difficult.Me I will try to built a simple modem for better use. These will be great toys for mobile HAM-Radio.

No signal via microphone in ios12, therefore useless on ios12 devices. No answer of developer to my emailMoney seems to be invested useless....

Impressive, easy to use, but the copy/paste function needs an overhaul. Once selected a text or call, the copy button is cancelled and disappears due to ongoing encoding.also, I miss the opportunity to copy the opposite callsign into a variable, so it can be used in the macros on the fly.in this state, qso are possible but typing the other stations callsign all the time is a pain.
