### 1/5 — Unusable

*2026-08-18, version 4.6.1*

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.

### 3/5 — Fonctionnel

*2026-08-16, version 4.6.1*

Je l’utilise en complément d’autres outils.

### 1/5 — Glitchy app

*2026-08-14, version 4.6.1*

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.

### 2/5 — Les cartes bathymétrique du nord du Quebec Canada ne sont pas existantes… Lac Matagami,olga,Goéland,

*2026-08-10, version 4.6.1*

Manque trop de cartes pour que je puisse les utiliser

### 1/5 — Waste of money

*2026-08-04, version 4.6.1*

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.

### 1/5 — Don’t bother

*2026-08-04, version 4.6.1*

I have been using this app for a while now and have overall found it great BUT after this last update it is unusable. I cannot even report the issue without it crashing so I am left paying for an app I can’t use and I can’t get help with. 
I can’t see my position.
I can’t track. 
I can’t navigate away from the page or the app forgets I was using it. 
And it crashes constantly. 
It is not functional as a navigational aid. Thank goodness it’s not my primary aid or I would be screwed.

### 1/5 — Works then not!

*2026-07-28, version 4.6.1*

Works sometimes but crashes frequently when ypu switch apps.   Today im pff san diego and i cant even get the app to start.  I have 5g,
I rebooted my phome and it starts and crashes before i het a map 5
Out of sox times.  The last time it gets a map,
Doesnt bring up a cours or roit and then crashes.   Im done. Cancelling subscription

### 5/5 — C-MAP

*2026-07-24, version 4.6.1*

Es una app bastante buena y completa uncluso mwjor q los ploters de algunos barcos

### 1/5 — Disappointed

*2026-07-10, version 4.6.1*

I did the free at first, then decided to do the paid version. Then when there was an update, it wiped out almost everything I had added . That is when I decided not to pay any longer.

### 1/5 — App freezes in settings

*2026-07-06, version 4.6.1*

App freezes every time I open setting using iphone 15 pro max. Will update review once developers fix.
