I used this today and the map did nor change when I traveled beyond the map view. I had to move the map myself. The developer responded with instructions! Click on the finger for compass mode I love having a GPS on my beloved Bizer map. Now all we need is tracking and night mode!!

I've been a lifetime boater on Lake Winnipesaukee and have always used the Bizer navigation charts. This app seems like a natural extension to be able to use my iPhone with the recognized name. We have found it very helpful for navigating around the lake, but there are improvements that it needs. Honestly, I was hoping that those improvements would've been done over the winter, but they remain to be seen. which makes you wonder about the viability of this app long-term if the company is not dedicating development resources to improving the user experience.You absolutely need to be able to save routes, which this app cannot do at this point. There's also no night mode, this is a big hindrance for using your phone for navigating at night because it destroys your night vision. Additionally, there's no way to change the orientation of the map while you're navigating. Many modern GPS apps allow you to choose showing north or the route at the top of the map, there is no option for this.I call this a good first effort, but like I said, it absolutely needs development resources for improvement.

Really makes navigation easy with lines to show you how to navigate through dangerous areas. Has MPH, auto zoom in and out based off speed, and auto rotate of the map. Unlike other navigation apps your location is towards the bottom of the screen which I love vs the middle of the screen where you see less of what’s ahead of you. Mainly use this for my jet ski so my kids know where they are and stay away from dangerous areas. Would be nice if they add additional features moving forward but for now it is well worth the price.

Ask any veteran laker and they will tell you not to go out on the lake without the Bizer navigator chart with you. I have found that this is the ONLY app that will show you where the unseen hazards are on the big lake. Other apps might show you where the black and red markers are, but I love that this app knows not to send you through dangerous areas like between pitch wood and stone dam island or between barndoor and little bar door islands. Great app! I won’t go on the water without it!
