### 1/5 — No support, no documentation

*2025-01-23*

I’m trying to get N2K data from my network displaying in my iPad but only some limited data elements will display.  My email to support went ignored and there does not appear to be any published documentation for the app.  For $20 this should be better supported…

### 5/5 — Versatile product

*2024-08-28*

I had some trouble setting up the connection but got speedy and excellent support from the developer. Still programming the details but so far all working fine. I run it on IPhone and iPad.

### 2/5 — Support seems to have gone

*2024-02-14*

I’ve submitted a couple of queries via the GitHub support page but no response in the last 2 months.

### 5/5 — Developer is very responsive

*2023-08-15*

Very good developer

### 5/5 — Great App - but can you use to local iPhone GPS?

*2023-05-08*

Really great App. Easy to connect, reliable, everything great but I don’t have a GPS on my boat so I’d like to use the iPhone GPS directly or connecting to a GPS server app such as GPS2IP. Is this configuration supported?

### 1/5 — UI needs help

*2021-04-03*

Once you get into map, can’t get out. User Experience Design is not a hobby, it takes actual development and knowledge about how to wireframe, prototype, test and deploy.  Expensive app to pay for for UX issues.

**Developer response:** Swipe at the top of the screen. I’ve been in the industry developing software for over 30 years, but thanks for the lecture!

### 5/5 — So glad I found this app

*2021-02-24*

This app saved me from complicating my system. I already had all the hardware I needed and this enabled me to get what I was needing out of it. It get the signal from my multiplexer, which for me is my Vesper, and all the NMEA 2000 sensors that feed into it. Thanks Scott.

### 1/5 — Wind Data not available

*2020-09-09*

I purchased the app to use and monitor wind data [among other data points], but the app does not parse $WIMWD nor $SDMDA messages.  I have a fairly new Simrad system (only 7yrs old) and these are the messages I need to view/monitor.  I tried using OpenCPN and they are parsed correctly by that application. Please add functionality for this in your app.  I emailed the developer and provided all necessary log and message data.  I am still waiting on a response.

### 5/5 — Excellent app and fast support!!

*2020-07-13*

I have a basic raymarine seatalk ng system on a sailboat. It includes a p70/ACU-200/EV-1 autopilot, wireless wind (T120 and T112), micro-talk gateway, Axiom 7 MFD, and YDWG. Not only can I see wind, gps, and rudder reference data in this app, but I can also control the autopilot!! It took only a few minutes to setup and even though I had the settings incorrect on my first go, Scott Bender’s advice fixed it right away. Definitely reach out before giving up!

### 5/5 — Fantastic

*2019-09-18*

This app represents a new step in bringing marine data into the hands of boat owners and anyone who has ever wanted to know more about the systems on their boat in a uniform, open manner.
