iPhone 7 problem

Updates ran with no problem but continue to receive 2 updates available message even though version shows correct. I’ve called and was told their aware of problem. 5 months later and still no fix. Apps on phone constantly updating but not once on this app. I would give this app 5 stars if humminbird would support and update problems.
This app is terrible! Same problems almost a year later. I mainly wanted this app for Bluetooth updates, which repeatedly alerts me to update back to old versions. I would give 1 star but great support staff carrying a dead duck.

HD Lake Master maps on my phone and tablet

The app is free which is awesome and it gives you satellite imagery of any lake you want to see. The in app purchase of an HD lake is easy and then gives you all the features just like the Humminbird units. Depth highlight, shallow water highlight, water level offset, make waypoints and routes. I use this app on my iPad so I can study lakes and plan trips from my couch. Also take the iPad on the boat and use the app to run the waypoints I made. Favorite feature is the quick ability to hide or show the HD map layers. Use the satellite imagery as the overlay then slide the circle at the lower right of the screen and see things others miss on the imagery.

Useful tool

I really like this app for the ease of scouting on my phone. I hate spending extra money on maps I feel I have already paid for with my lakemaster chip, but I think it was worth it for my most fished lakes.

Where this app could improve:

Why can’t we select all of the waypoints from a route and hide them all at once? Selecting 100 waypoints individually and hiding them is a PAIN

Why does the app need to validate my purchase every time I open the app? This process takes too long.

I wish it would give me the option to rename a waypoint right when I create it. Having to go in and edit it just adds more steps. I don’t think most people use the default naming convention.

It would be nice if we could zoom in as far as you can in google earth.

Why can’t we upload waypoints/routes to our graphs just like uploading FW to the unit via BT?

I use this on my iPad and my iPhone. Why can’t we have a setting to link my devices to share the waypoints between them?

You solve these issues and it’s a home run.
