Designed to work with Digital Yacht's iKommunicate Signal K gateway, Signal View turns an iPhone (or iPad running the iPhone version) into a portable multi-function display for your boat. Signal View makes it easy to check tank levels while fuelling or filling, monitor drift and depth while fishing or relaxing, or even to calculate optimal fuel economy for two separate speed ranges and engines.

Thanks to the new Signal K standard, that previously inaccessible boat data on your boat's network or multi-function display can now be viewed on your iPhone. The Signal View App supports data from any brand of electronics so long as it outputs NMEA 2000 or NMEA 0183 formatted data. Signal View fulfills the promise of live boat data in your pocket from any NMEA 2000 network!

60+ data types supported. Data that can be displayed includes - navigation, communications, propulsion (rpm, fuel flow, oil pressure, temperature, hours, etc), environment, tanks, batteries. There is a full list at the support website: SIGNALKOOL dot COM slash SIGNALVIEW

YOU NEED AN iKOMMUNICATE FROM DIGITAL YACHT TO USE THIS APP! (Requires iKommunicate firmware dated Feb 15, 2017 or newer). It may have reduced functionality with other Signal K servers.

*This App was independently developed by Adam Hyde. Although it is designed to work closely with the iKommunicate from Digital Yacht, the developer is completely independent from the company. Please do not contact Digital Yacht for support. Use our App store support link.

Functionality includes:

- Four custom screens with 16 custom labeled data values. Screens can be automatically emailed at the frequency you set.

- Engine monitoring with multi-engine support (4 engine maximum).

- Pre-configured "fish" screen for drift-fishing or anchor-watch with configurable alarm for drift distance. You an also set an email to trigger if the alarm triggers.

- Fuel economy calculation per engine or combined for dual engines with 9 different calculations possible including: L/km, L/NM, L/m, km/US g, NM/US g, m/US g, km/g, NM/g, m/g.

- Set minimum planing speed on a planing hull for both displacement and on-plane optimal fuel economy. Signal View calculates what RPM is the most fuel efficient as you run your boat through its throttle range.

- Maximum range calculation (planing and non-planing) based on fuel economy and estimated fuel remaining (if fuel flow, RPM, and speedOverGround are present).

- Built in alarms for drift distance and engine temperature. Drift alarm can email a notification.

- Engine temperature monitoring (displays peak temperature reached with quick reset by touching the value) with configurable over-temperature alarm.

- Send your boat's current location via email, sms, or twitter. It uses your boats GPS data unless it is not available. With no GPS data, Signal View uses location services on the iPhone as a backup only.

- Metric, US and Imperial units.

- Automatic discovery of iKommunicate on your network.

- Built-in activation of your iKommunicate's internal logging for diagnostic purposes (Telnet software not required).

- View iKommunicate's SD card storage space used.

- Manual IP address override for remote testing or using with other Signal K servers (might not work 100% with other servers).

- One button to view your boat's raw data in Signal K format. Raw JSON data is sent with automatic emails so you can process it off the boat for website updates, etc.

- Data updates approximately once every second.

You will need NMEA 2000 or NMEA 0183 data, the iKommunicate by Digital Yacht, and a wireless router and this iPhone App. No Internet connection required. Signal View communicates with the iKommunicate using WiFi from your on-board wireless router.

Please report issues at the support website. Enjoy!

What's New

Version 1.0.1

-Fixed engine temperature not displaying with latest firmware update (engineTemperature was internally changed to temperature by Digital Yacht).
This version now needs iKommunicate firmware dated March 20, 2017 or newer.

-Added a cancel option after you choose to send your location in the tools page.
-Fixed altitude so it displays the correct data - not latitude.

Ratings and Reviews

Exceptionally useful!

MV Easy Living

Here is an app that is exceptionally useful for power boats written by someone who understands fuel efficiency. The Engine page shows current engine gauges with fuel flow optimization.
The Drift page is designed for drift fishing and as an anchor alarm.
There is a Custom page that allows you to display any user defined SignalK data such as tank levels.
