User Reviews

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.

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.

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.
