### 1/5 — Day sailing

*2026-08-22, version 176.0.0*

The margin in errors is way too much, from 150 m to 350 m even with all the settings to max precision, I think you need a internet connection all the time I used 5 G an that was the result for a day sailor not good

### 5/5 — Navionics can go to hell

*2026-08-19, version 176.0.0*

amazing app

### 1/5 — Position wrong

*2026-08-19, version 176.0.0*

Won’t show my true location

### 2/5 — Not user friendly

*2026-08-17, version 175.0.0*

It keeps saying another route is in edit when I want to relate a new route. There is no other route so why it says route in edit !?.
I turn the app completely off then it works for while then back to its old tricks. I am not paying for this app.

### 1/5 — Customer support

*2026-08-15, version 175.0.0*

The product seems to be very good so far. However, customer support sucks. I have sent messages via the listed email address and the suggested Facebook page weeks ago and have not received a response.

### 1/5 — I paid for the app once I’m not paying again

*2026-08-08, version 174.0.0*

What a slimy outfit I already paid for a subscription once use the app several times and then it went into upgrade mode I assume because they could tell I was using it on occasion Then they want another $44 Canadian or else I can’t use it. What a joke as far as I am concerned, you can piss off.

### 5/5 — Great App

*2026-08-08, version 174.0.0*

It does what we needed it for and we can upgrade maps if needed in the future. QGreat for novices, imho.

### 1/5 — STAY AWAY

*2026-08-08, version 174.0.0*

Their support email does NOT answer emails. I’ve been emailing them for over a year about a license reset and they have ignored each email. Utterly disgraceful.

### 1/5 — Annual mall fees

*2026-08-06, version 174.0.0*

This is a good app, my complaint is that I purchased a map, had a bunch of pins dropped on it. And nowhere did it say this is an annual purchase. Plus all my pins are gone. Won’t be purchasing a map again this year.

### 1/5 — Scam and fraud

*2026-08-06*

I paid for lifetime Russian maps. Then you deleted it. Now I can't use program at all. Give me my maps back, frauders!
