Professional Level Navigation App

I have been using this app for nearly three years now for professional work on yachts and it has yet to fail me.

As with all navigation, I strongly advise users have two different and independent devices running this same app. I, for example, use an iPad Air 2 and an iPhone 7, and for positioning information I use a Garmin GLO and a Bad Elf 2200 GPS signal receiver. The Garmin GLO has temporarily shut down in the past, so it is essential to have the other device running especially when operating in hazardous areas like busy channels, near shoals or barely submerged hazards such as wrecks or isolated rocks.

The main improvement I would recommend to Bist LLC at this time would be to offer an in-app purchase cruising guide feature that would enable the user to access critical information about facilities (such as good phone numbers, radio channels etc) by virtue of simply touching the facility name on the current ECS. In the event of emergencies, be they weather or mechanical etc, it would be extremely useful to be able to immediately find the phone number or radio contact information for potential landing sites like marinas.

Lake depth maps

Very user friendly app to download lake depth maps and coastal charts. GPS features including recording and moving map works very well and is very reliable. The support is very helpful and answered all the questions I had. I had asked them about a specific lake that was missing. To my pleasant surprise they contacted me today to let me know that they had added depth contours for it and it was a available for download.

Update1: I’ve used it quite often in sf a yas well as Sac delta. For navigating the Sac delta I wasn’t able to identify the deep channel. The support was very helpful and suggested me to change the shallow and safety depths. Once I did that I was able to identify the deep channel. I plan to use it in Shasta next week. I am glad they cover it. Will update the review with more details next week.

I like the app but the update feels like extortion

I really do like this app and would have rated it higher if it wasn’t asking me to pay ANOTHER $20 for the update.

I bought the app last year for $22 including tax. It’s the most I’ve ever paid for an app. It kind of goes against the grain for me because so many apps I’ve had in the past and relied on have either been bought by another developer or have ceased to exist. So to come back a year later and require I purchase it again just to keep using it is a hard pill to swallow!

I can understand the cost of the map update but to stop the functions of my already purchased map to me is truly unfair. Sure I can navigate using existing routes I created but not allowing me to edit or create new routes using my existing map that I already paid for is not right. Seems like extortion to me. For this reason I don’t want to pay for an update.
