HOW SURE ARE WE
Lower confidence: this app ranks below the overall top 50 everywhere, where single estimates can be off 2 to 4 times. The range is wide on purpose. 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.

★★★★★Oct 19, 2026

Really glad they came out with an Android version. I bought an Android tablet with a giant battery that is also waterproof to 6 feet. The integration with the Furuno first watch radar is very nice. I originally purchased an iPad and an iPad mini and an iPhone to experiment with the TZ iboat app. No matter how hard I try I can't get my brain to think Apple... so, now I don't have to and that is wonderful. I'm enjoying this app very much. depth shading has been handy for fishing.

★★★★★Oct 9, 2026

best navigation app for sailors very well thought through, complete and easy to use. vector and raster charts are a welcome idea, and I really like the way ais targets and CPA are displayed.

★★★★★Oct 5, 2026

very detailed 👌 I used it for free and ended up keeping it even tho I have GPS on my boat. Just good as back up.

★★★★★Oct 4, 2026

Completely unusable. Every time I try to open the app, I get an "application could not be verified" error message and it won't load past the splash screen. Total waste of time and download data. Fix your security certificates or whatever is causing this bug!

★★★★★Sep 30, 2026

insanse technology for the hard core fishermen.

★★★★★Sep 17, 2026
