Unusable

The app is unstable and crashes unexpectedly, even though it is already updated to the latest version.

The cursor showing my current position does not appear.

The track recording randomly freezes, even though I have granted the app location access set to Always.

I am extremely frustrated to have paid so much for an app that is ultimately completely unusable.

Fonctionnel

Je l’utilise en complément d’autres outils.

Glitchy app

App shuts off seconds after being opened. It does this repeatedly before it actually stabilizes. Then routing is far more finicky than the garmin app.

Les cartes bathymétrique du nord du Quebec Canada ne sont pas existantes… Lac Matagami,olga,Goéland,

Manque trop de cartes pour que je puisse les utiliser

Waste of money

I have tried to use this app for a couple of seasons. At the start it worked fine and was quite useful. Last season, it would lose track of my location usually in important areas, like where I needed to know where I was to set anchor versus running aground or narrow channels with poor markings. This season , it won’t show my location on the map at all. This is a basic map function! I have deleted the app and re- downloaded it with the same issues. I want my money back and will use another app.
