HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (1.2 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Looks great6%

13 of the 4 and 5 star reviews.

Restore not working, no response, a shame

I have purchased a set of charts this spring with a 1 yr subscription. And I want to install it on my 3 devices, 2 iPads and an iPhone. The restore finally worked after several attempts on the iPhone, but fails on the second iPad. This has been going on for months. I have written an email to the address they provide here, but no response for several weeks. The support and updates have really gone down since the app was taken over by Wärtislä. It is a shame. Why have they taken over this app if they do not care about the app and its customers? I have used iSailor for more than 15 years and it still works better for me than the others on the market. Thats why I am so deeply disappointed. If I had no problem switching I would say, what the hell, I will not use it anymore. But I want to use it. It is a real shame how longtime dustomers are abandoned to the point where they switch to another app even if they like the app itself. My question to Wärtisilä: Why did you purchase this app and take it away from an engaged team which was responsive and helpful? And obviously do not care anymore? Although I still like this app better than the others I know, I will now make a deeper research for an alternative. Marcus

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.

Active Unlock AIS Option

Kindly requested to active AIS options to be used with new navigation equipments. In new devicee we receive ship data through AIVOD sentencesb that unfortunately that is locked in the app.

No download of purchased maps possible

Be aware: even if you once you purchased a map you later will be forced to rent it

★★★★★Dec 30, 2025
Bisher gut dann plötzlich kein Download möglich und somit unbrauchbar!!

Letztes Jahr im September 25 wollte ich wir jedes Jahr Karten laden um am nächsten Tag auf 3wöchigen Törn nach Kroatien zu starten aber es war einfach kein Download der Karte möglich! Für mehrere Tage!!! Natürlich hab ich Papierkarten an Bord aber ist einfach sicherer zusätzlich mit Nav-App. Zumindest wenn man die notwendigen Karten laden kann! Aber das war nicht möglich und so musste ich eine Konkurenz-App kaufen welche zwar teurer war aber mit der alles auf Anhieb reibungslos geklappt hat. Ich habe nun gelesen dass es da angeblich Probleme wegen hohem Andrang gab aber das darf einfach nicht passieren! Erreichen konnte ich auch niemanden und keine Reklamation möglich. Meine Vermutung ist dass alle im Urlaub waren Ende August Anfang September. Da haben die Kunden/User eben Pech gehabt! Sehr schade denn war viele Jahre lang super aber ein derartiger Schnitzer und man verliert eben Kunden. Mich zum Beispiel …

Kein GPS Signal

Die APP akzeptiert kein GPS Signal vom iPhone. Google Maps und Navionics geht. Schade: Geldverschwendung.
