Actually rather good nav app
MeerI have used the app several years now. A very frustrating period hopefully lays behind, as charts could not be updated, and the chart store was completely dead.
However the UI was quite good and clear, also for AIS
Things seem to have improved since spring 2025, charts can be updated and bought. So far it is (one of) my favorite nav apps.4door Ohf*****20/09/2025App seems to be working again
MeerThe app used to be very good with high quality charts. Since the Wärtsila takeover the app appeared to be almost braindead and loading or updating charts was not possible.
In the mean time (summer 2025) things seam to have improved. Buying or refreshing charts is again possible. AIS works ok. Hoeever on some charts recent updates are not visible >> f.i. Port of Dover: Granville dock does not exist anymore.2door Wer*******29/08/2025Still a great App - Please update it
MeerTried Navionics Boating app this season, sailing on the North Sea and UK south coast. Found myself constantly going back to iSailor. AIS integration works much better. Including your own position. Can’t believe how poorly this is done in the Boating app. Chart display could really do with an upgrade, especially showing the wind farms when zoomed out for passage planning. The are all over the place nowadays.
Thank you.5door Mic*******23/08/2024Worst system
MeerVery unsatisfied. Customer service doesn’t react. I spend €64 and it turns out to be impossible to restore our charts. Money thrown away.
1door Ott*******07/05/2024Chart Server Down
MeerAll ready a long time professional user of at first Transas and later Wartsila products. Both the ISailor app which I use for route planning but also of the professional ECDIS systems. At least since last week 30/04/2024 the chart server is down. Charts can be ordered, paid but will not load to the iPad as when trying to download an error occurs (pls try download later). Tried to contact Wartsila but without avail. Meanwhile, besides not having the charts as requested, also the subscription time is counting down.
Wartsila, pls correct the situation and get the chart server up and running again.3door Cap*******06/05/2024Unable to Connect to netwerk
MeerIssue: Don’t know why but ISailor Seems to fail to connect with an internet network. Not able to restore purchased cards or to add additional subscribtions wrt ais, tide and so on.
Tried this with 2 different iPads, with the same results.
I am a fan of this program and using it already for years. Now very worried.
Is there an issue wrt the latest upgrade of iOS?2door Ale*******31/03/2024Support does not give reaction.
MeerI bought a chart for €30. But is is not working.
Support gives me an automatic ticket number, but does not react for weeks.
Advice: do not not update your charts but search for an other app.
Kind regards Martin.1door Mar*******01/03/2024No chart updates possible anymore
MeerSince 4 year we have to pay for updates which was ridiculous.
Now updates are not possible and available anymore.
Wärtsilä please supply chart updates or at least inform your customers, you are bringing ships in danger this way!1door Jou****24/07/2022Not updated for many years
MeerThis app looks like it had been abandoned as it has not been updated for many years and now risks being removed by Apple. There are issues with updating maps with a valid subscription that have been known by the developer for almost a year but have not been solved. This used to be a great navigation app, but unfortunately I can no longer recommend it until it gets a much needed update.
2door J S******25/04/2022Charts not updated
MeerIn the Netherlands we have the Waddenzee, which is a “living area” with moving sandbanks. The charts haven’t been updated since 2 years. Also new windmill farm offshore is not on the map. What am I paying for
1door Bij*****21/03/2022Chart updates are not current!
MeerChart updates are not current. They miss full wind parks that really aren’t built in a day. Getting more and more dangerous to use iSailor!
1door Kui***17/10/2021Software life-cycle finished
MeerNormal software life-cycle: built by a genius, then deteriorating after selling ng to financial, legal and technical misbehavior… A common software evolution disaster…!
1door Mik*******13/07/2021Good for Waddenzee, useless for Friesland
MeerI bought the Friesland map. Because I like the waddenzee map. But the Friesland map is very bad quality. The zoom is not working, so there is no overview. Do not buy the Friesland map.
The Waddenzee costs €20 each year and is updated about 4 times a year. That is OK3door Mar*******15/06/2021Criminelen
MeerIk had voor €250,00 aan kaarten gekocht. Toen werden de updates betaald. Heb niet gedaan. Nu zijn de kaarten gewoon weg.
Weg geld. Het zijn gewoon bedriegers1door Dop****08/05/2021Niet kopen !
MeerIn december 2020 gekocht en op mijn iPad geïnstalleerd, pakt niet over op mijn iPhone . Recent een nieuwe iPad aangeschaft, maar pakt ook hierop niet over: €21 weg nu !
1door App*******04/04/2021I like it. 2000+ offshore miles.
MeerI really like the app. It works great with ais projection on the chart. The alarms are amazing and life saving on several occasions. The charts are relatively cheap.
Update: I’ve purchased charts for The Gambia and Saint Vincent, there are no charts shown, I had this also in roscoff but thought it was an exception. Apperantly it is not. Why are these detailed charts missing?
One thing I’ve been wondering: are the routes great circle routes?
FOR THE DEVELOPERs: In terms of alarms the only thing I am missing is an alarm on the speed. This would be a great way to be triggered on a wind increase. If I am sailing along at sea I try to reach optimal speed. This is around 5,5 knots. If I got to sleep /at night I reduce sail because I don’t want to continuesly keep watch. If the wind would increase so could the speed creating possibly a dangerous situation. If however the speed would be monitored I could leave extra sail in the night resulting in 10-20’extra miles per day.2door Ben*******19/01/2021Outdated charts even with active subscription
MeerToday, after navigating into a tricky area, I found out that the charts are out of date. Even with an active subscription. The only way to update seems to be uninstalling and reinstalling the complete app. This is unacceptable. There should be a better way of checking for updates than comparing the charts with other iSailor users. When iSailor tells me that the charts are up to date I should be able to trust they are.
2door Ari******23/08/2020Abondonware
MeerNot updated in years, not even support for last gen iPad Pro or any gen notched iPhone, X and higher. This company promised to keep chart updates free for people who bought charts before November 2018 but this year suddenly decided not to keep that promise. Don’t trust this app for anything.
