PSK31 QSO - how to transmit?

Reading is fine, but now I want to transmit. I couldยดt figure out how to transmit.

It does work, but it still needs work...

As I review this app, it appears that PSKer (which frankly has better functionality) has stopped working all together since the developer of that app stopped updating it years ago and now that app doesnโ€™t accept audio input (needs permissions fix to be current with iOS).

This app does work, but is a little rough around the edges. I wish it supported landscape mode for the iPad, tagging of waterfalls, and a more intuitive interface.

In short, this is all we have for PSK on iOS right now and...at least it works, but still - wish the app would be updated. Iโ€™d gladly pay for it. 73, KI4ASK

No working

Doesn't working well on iOS 11. Throw away to the trash box.

It works, but....

It does work with my Easy Digi by KF5INZ interface. Main problem I have is that you can not change the rotation of the app. I use it with an iPad Pro connected to a keyboard case. The will not display in landscape orientation (sideways), only in portrait mode.

This makes the waterfall display small and I have to use the iPad outside of keyboard case.

If it would display in landscape orientation with a larger waterfall, then I would use it more.

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.
