User reviews

Fair winds and following seas

This app is super useful. I love that I can get basic speed on my watch and a few other goodies without a subscription. Yay for Hull Speed!

A super accurate and reliable speedometer

This app works great when kayaking even though it’s designed for sailing. It’s better than the app I was paying a monthly fee to use.

Response from developer

Thanks for your kind review. While I designed it for sailing specifically, it's good to hear it works well for Kayaking as well!

Bravo!

Exactly what I was looking for! Accurate speed and course on the Apple Watch, no silly subscription, just a clean one-time purchase. And it works amazingly well! Kudos to the dev for building a truly useful Apple Watch app without a lot of cruft or an unnecessary subscription.

Response from developer

Thanks for taking time to write a review. You hit the nail on the head - this is exactly why I made the app! I'm glad it is working well for you.

Just what I was looking for

This is just what I wanted.
A simple straightforward speedometer I could run on my Apple Watch, that won’t disappear when the screen locks, and doesn’t try to do too many fact things I don’t need. The live activity is a nice touch too. Best of all no subscriptions.
