Eh.....well if nothing else

Okay. So I tried this with PSK31 and it works 'okay' but not the greatest. It will not copy PSK63.

It would be great to have something like fldigi for iOS.


Needs major update

Please add support for Apple Watch.

Doesn't do a good job decoding.

Needs ability to transmit as well.
