Navigera Sommen

Uncomplicated GPS navigation adapted only for lake Sommen on the border between Småland and Östergötland. Contains the new beautiful and easy-to-read chart that Sommens Segelsällskap produced this year. This card is sold solely by the club and is a paper card.
There is not yet a working GPS version with this card on the market. The app here that contains that particular card is made by an amateur. It has very simple functions and works without advanced equipment. A simple Android phone will do.
The map that you see in this free app is completely blank and empty of all information for navigation. It therefore lacks depth curves.
The real chart with the entire Sommen lake on a single sheet is already included in the app. To access it, a ransom is required. This redemption can only be given to users who bought a card on paper.
The redemption can be obtained from the Sailing Society for a small fee, a one-time fee, which will still be lower than what other companies can offer. This fee goes directly to Sommens Segelsällskap.
On the SSS website under the heading 'Chart' at the bottom you will find information on how to get the real chart into the app.

No internet connection needed.
Low power. The screen automatically goes down to low brightness.

The app is only available for Android. Unfortunately will never be available for the IPhone.
Should also work on reasonably old devices.

Get the app now, completely free. Get to know it by navigating on land around the lake, on foot, by bike or by car. GPS only works as long as you are on the map. When you get home, you can see a track drawn over your journey.

Get in touch with your comments here on the I need to hear page if something doesn't work and if something should be changed or added.

One of the pictures shows 6 of my old phones running at my house. GPS functionality works on such simple devices as a 10-year-old cheap Samsung. Other phones are the Huawei P20 and P30. Two different Doro and an ancient Nexus tablet with crude graphics.
