### 1/5 — Dreadful

*2026-08-14, version 4.6.1*

Paid the GBP 42 to move to premium and everything is still locked down

### 2/5 — Almost worthless

*2026-08-11, version 4.6.1*

Can’t access setup. All I ever get is the little spinning wheel. So app is worthless. Been like this for months.

### 1/5 — Unusable

*2026-08-09, version 4.6.1*

Crashes within 20 seconds of opening — the app is unusable.

### 1/5 — Poor functionality

*2026-08-09, version 4.6.1*

This is not a well made app, cannot currently confirm my home harbour which is frustrating. App will not let you part complete a form so you end up re entering information over and again.

### 2/5 — Many issues

*2026-08-01, version 4.6.1*

Warning! I thought i would give this app a chance and choose the two week free trial, but unfortunately it charged me straight away so I guess the two week trial was simply false marketing?!

When using the app I can’t even create a route. The app gets stuck when I click the route button.

### 1/5 — This app sucks

*2026-07-30, version 4.6.1*

The app constantly crashes.  I delete and reinstall and still it crashes.  Fix your garbage app.

### 1/5 — Die App stürzt ständig ab

*2026-07-29*

Die App hat mir eigentlich gut gefallen, so dass ich sogar die Premium-Funktion gekauft habe. Nun stürzt die App jedoch leider ständig (mehrmals täglich) ab, was sie leider wertlos macht. Ich hoffe, das Problem wird bald behoben.

### 1/5 — Very disappointed

*2026-07-28, version 4.6.1*

My immediate reaction after using the app is that its display of depth has weird fonts that make it impossible to read or be confident in planning routes.  Also, basic navigation and route planning is extremely glitchy.  I don’t think I’d trust this at all.  I’ll play with a little more, but highly unlikely to depend on it, or pay for it.

### 2/5 — Very buggy App

*2026-07-18, version 4.6.1*

I wish I could’ve shared this information through support, but there is no support communication option for the companion app according to the knowledge base and any information posted in the app support link provided here. The app is extremely buggy the icon a circle that represents my position often just doesn’t show up every time you touch the screen. Often when touching the screen to zoom or move it thinks you’re putting a mark down. Most of the function in the UI is just not well planned and up to par with so many other Apple apps.  I am hopeful that B&G will make a proper investment and get this app up to snuff.

### 1/5 — Disappointed

*2026-07-14, version 4.6.1*

Just upgraded at 70$/year and not impressed. It crashes you can’t see forecasted weather along the route based on your plan. Basic features that an App from B&G should have. Other apps made by private people are much better. A lot of issues with the GPS signals while other apps run at the same time don’t have. I wish I could be reimbursed. Can you hear me??? The worst upgrade I have ever done
