### 5/5 — MAC and IOS apps for Control of the Elecraft K4

*2026-02-26*

Like most Apple software, K-4 Control is both innovative and intuitive. It is also easy to learn and use. You are definitely not looking at a long learning curve with these apps. A good example is the FT8/FT4 mode which makes operating those digital modes both simple and foolproof. No audio drivers or settings required. You will be up and running FT8 contacts in a few minutes. I started with the MAC app several months ago and was so pleased I got myself an iPad for more flexibility. When I ran into a connection problem support by Marcus was prompt and unstinting. You will NOT be abandoned. Highly recommended.

### 5/5 — The Best

*2026-01-16*

Marcus never fails us to bring another outstanding remote app. Works seamlessly with the K4D.

### 5/5 — Outstanding as usual!

*2025-12-15*

I have owned Marcus’s apps for the Flex 6400 Radio for iOS , iPadOS and macOS before. His MacOS app is much better than Flex’s in-house Windows app. Now I have a K4D and first day on the iPadOS version and Marcus does not disappoint. He is an amazing developer. I highly recommend this app.

### 5/5 — Highly Recommended

*2025-06-30*

Really appreciate what a fine product this app is.  Had a few questions on getting Remote to work from outside of my home’s LAN.   The support and assistance I received from this app’s support team was absolutely excellent.
