SEAiq

Impressive number of professional-grade nautical navigation tools right on your personal device, and the ability to import your own ENC charts. Great product - very well done!

Creating routes and waypoints a bit clunky. A few options hard to find. Learning curve a bit steep, but does allow CHS charts, but US charts take priority rather than being selectable.

I purchased this app more than a year ago and it was working fine with my CM93 charts, but since last update they have removed the reason why I had bought this app and it is now perfectly useless without my charts... Once again we get screwed by updates and a waste of my money

This app has many more features than other Nav apps and I used it last year in preference to all others. Unfortunately, the most recent upgrade removes support for cm93 charts. It is always disheartening when an app developer makes changes that decrease the value of the app for customers that have already paid good dollars for it.

Don't bother getting this app after developers stopped supporting CM93 maps.. The app now is worthless So bad

Seaiq is awesome, keep it up!

When i try to delete this program, it freezes my ipad ii. Have reset the ipad to recover.

It's a cute app. I enjoyed checking out the 7 day trial, but paying 40 dollars to be able to create waypoints is brutally expensive. 10 dollars and you would have had me... Especially considering the cost of the charts on top of the application. Nice work on the app though, and if you ever lower the price I'll buy it, but 40 dollars is not worth it. Thanks.

I have logged over 10k offshore sailing miles on SEAiq and consider it an essential piece of equipment. I highly recommend it to boaters wanting a highly reliable navigation app, which boasts tons of features in a clean and sensical interface. To start, it is incomparably more versatile than Navionics for plotting routes and waypoints, estimating AIS target crossing range, as well as visualizing vessel data. For the last bit I use a YDWR02 NMEA-Wifi router, which wirelessly transmits all vessel sensor output to SEAiq on my iPads (such as GPS, speed, wind, depth, etc.). Features I especially appreciate include ‘NMEA data smoothing’ (for an easier read on COG/AWS/SOG) and the ability to switch into ‘dark mode’ (to preserve your night vision). The app allows you to modify all kinds of parameters, enable alarms (wind speed, depth, AIS, anchor, etc.) and check tides, to name a few. Similar to OpenCPN, you can also load custom satellite charts (.kap files from GoogleEarth or VentureFarther) which are invaluable when navigating in places where vector charts are inaccurate (ie. Navionics in Fiji) and/or when anchoring around rocks/coral reefs. You can also load vector charts from subscription-based services like ChartWorld or NZ ENC, although I did find it quite complicated to setup initially (‘certificates’ and ‘user permits’ are required for each device). As a result, I often use SEAiq in tandem with Navionics while navigating in coastal waters, as the latter still offers great chart detail in most places. On the other hand, if you don’t plan on leaving US territorial waters, the NOAA charts in SEAiq are free and very easy to load. Furthermore, all chart files and tracks are saved in an easily accessible folder, so you can backup, modify or share them across devices. I have never had any charts accidentally disappear, nor has the app ever crashed on me (unlike Navionics, which does so constantly). Lastly, I am thankful to the developer, who was quick to answer any questions I have had thus far. The only request I would have is to add support for .MBTiles :) Thanks and keep up the good work! Highly recommend.

We use SEAIQ and Navionics on a daily basis. Navionics primarily for new harbors in the US due to their sonar charts but we use SEAIQ whenever underway outside the harbor. There is room for improvement but likely features I am interested are geared towards weekend cruises whereas SEAIQ is focused on professionals. I still love it though.
