Just released this week: DragQueen - a free
anchor alarm. It has been installed by over 1,000 people already this week. We used it for 2 months at
anchor before releasing it to the app store. I'm the developer. An Android version is already working from the same source and will be in the Android Market in a few weeks - also free. I intend to release the source code for it too with no
license so anyone else can take it and enhance it, add to it, whatever.
There are some really interesting and new chartplotting apps coming in early 2012. These apps are so relatively inexpensive that it's worthwhile getting a few. I'm currently working with at least 4 iOS developers on products that aren't on the market yet. One in particular is an incredible product.
I personally like Navimatics
Charts & Tides a lot - they have great ActiveCaptain support. There is a fantastic competitor coming for the popular
Navionics products - if you can wait a little, hold off.
Get all the
weather apps you can get - a variety are excellent. I only paid for Weather4D which I like when I have a
WiFi connection. WeatherBug is the one I generally go to for
radar and forecasts.
I'm developing a very large app that will act as a companion to your
chartplotter. It's unlike anything else and doesn't really compete with anything right now. It'll also be free on Windows, Mac, iOS, Android, and SmartTV. It supports phones and tablet sized screens. DragQueen was an
experiment using this multi-platform development technique to produce real
GPS apps for the various app stores. This upcoming Companion product will also be free.
