Excellent

Excellente app de navigation, interface simple, rapide et fiable. Bien plus claire et facile que les concurrents.

Prix des achats intégrés très corrects.

Je viens d’investir dans un transpondeur AIS (émetteur / récepteur) : je reçois toutes les donnes sur l’application (iPad et / ou iPhone). J’ai également les notifications des alarmes sur mon Apple Watch.

L’apport pour mon voilier est vraiment incroyable pour ce prix.

Merci

本船ais轮廓不显示

新版本更新后,购买ais 功能,只显示他船ais轮廓及航向和航速,本船只能使用内置GPS显示航向和船位,本船ais数据不能接收,这点给航行及靠离泊带来极大的不方便,希望后期更新

Chart Loading is broken

Trying to update charts and Restore function does not download charts properly

Good looking but always broken

I always keep coming back to this app because it’s cheap to get into it (until you realize every other button is a paid upgrade).

Latest issue for me is that this app can’t import routes.

Detail vanishes randomly from purchased charts.

You buy a chart and expect that what you’ve purchased remains intact, but it doesn’t. It degrades as they pull detailed data that you’ve already paid for. You’d expect purchased updates to provide the latest survey data, and by all rights they do — but if you don’t need the latest and greatest survey data, you’d expect the old charts you bought to show you everything you bought. Nope — they pull the rug out from underneath you and dangle a $6 chart upgrade out there with no guarantee that the corrupted view of the area of interest will be any improved after taking the bait. I’m done with this app. Open CPN on raspberry pi it is.
