## PSK31 Reviews in United States

### ***-- "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 doesn’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.  I’d gladly pay for it.  73, KI4ASK

### **--- "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.

### *---- "Needs major update"
Please add support for Apple Watch. 

Doesn't do a good job decoding. 

Needs ability to transmit as well.
-- TheGadgetinator, 2016-09-27

### *---- "Too Noise Sensitive"
Too noise sensitive to really be of any use.
-- fteter, 2015-09-03

### ***-- "Not the easiest to use"
Noise sensitive and difficult to transmit
-- rich52, 2015-04-03

### ***** "Great!"
Another works as advertised... Ready to buy an upgrade with transmit! Thank you!
-- RKMoe, 2010-12-29

### ***** "Slick!"
Works great.  Much better at decoding than my previous iPad app.   
Runs fine using the speaker and internal microphone but really works well when I plug my iMic USB sound card in to the camera adaptor USB port.
Using it to decode the signal and the ability of the K3 to send PSK with paddles makes for a slick little, computer-less, PSK station.
-- rprather, 2010-09-30

### ***** "Works as described!"
Really enjoy this app, simple and easy to use! Maybe in the next version a TX mode!
-- Onkel Art, 2010-09-16

### ****- "PSK31"
A very cool app ... Thanks ... Works as advertised
