Excellent addition to my boat safety equipment

I have a mount on my helm for my phone just so I can use the app. I prefer it to the radar and 2 separate garmin units when I want this information.

Boat Speed

Just moved from Droid to iPhone and discovered that useful app (SailDroid) on previous device was probably named for the platform it runs on .. imagine my disappointment when I discovered that it isn’t available for the iPhone!
So I searched the App Store and selected this “turkey” .. So, now you’re asking why I have described it as a turkey .. so I’ll ask you, how would you characterize an App that displays a varying velocity from 0-2.6 knots while you are sitting stationary on your couch. If I can’t rely on it sitting stationary on shore how can I trust it bobbing out on the ocean blue.
I’m going to contact the AppStore and ask for my money back!

Developer Response ,

I’m very sorry your having trouble viewing a consistent speed in the app. BoatSpeed relies on your iPhone’s GPS chip to show your current speed. When you are indoors on on a couch, your iPhone cannot maintain a good GPS signal and could show a fluctuation in speed even when you are not moving. The speed shown is the app is shown exactly as it is detected by your iPhone.

Please know I test and use the app regularly on my boat and in my car and find it to be incredibly accurate when moving consistently.

Before requesting a refund I ask you to please try using the app when you are outdoors and moving and let me know if you continue to have trouble. I can always be reached by email at
