This program is distributed in the hope that it will be useful. PowerBoatguy should only be used for basic navigation reference and should not be relied on solely to determine precise locations, proximity, distance or direction. Continued use of GPS running in the background can dramatically decrease batterly life.

Ratings and Reviews

If it would work correctly it would be awesome!


I love the idea of this app and I would love the app if it would work properly..... but it rarely does. I can record my trips and holeshots but I can’t view them. The holeshots will not come up at all. Also I recorded a trip this past weekend, and I was able to view it that night and I think I looked at it Monday morning but now it’s Tuesday and it will not let me open it or pin it to the home screen. And I have recorded 2 holeshots and have never been able to view them. Also I used the speedometer Sunday and I was turning about 2800 rpm and it was saying I was going like 36mph. I wish that were true but sadly no, my boat does about 27-29mph. And at WOT it was saying over 60mph. There was a few people with me and it’s only gone over 50mph once and there was only me in it. So I restarted the app and my iPhone and it corrected that but still can’t view my saved info.
Fix these problems and u will get a 5 star rating from me and I will absolutely recommend this app to every boat owner I know. If it worked like it is supposed to then it would be my favorite app ever! Please fix it, or if it’s user error please tell me what I’m doing wrong!! So yeah I give a 5 star rating for the idea and initiative, but a 2 star rating for execution. It’s all great features just make them work and I’m in with 5 stars!
