Good

It is a good and well priced app. The only problem I have I cannot swipe to the third screen on iPhone 13 mini. It keeps scrolling the map on 2nd screen instead.

Response from developer

Thanks for letting me know about this - I hadn't tested on the Mini. I will look into it. On my iPhone 17 pro I can scroll to the 3rd screen by tapping on the speed/distance display or the map color legend. I assumed you could do so on the mini as well. Feel free to send me an email and I can send you a beta version to test. EDIT: I tested this on a simulated iPhone 13 mini and it works exactly the same as other devices. To navigate between the screens tap and drag on the legend at the bottom, not the map itself. If you need more help feel free to reach out to me and I can definitely help you with this.

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!

Thanks for your review. I'm happy to know you like the app!

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.

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.

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.

Great for the Lake

This App is great for a quick sail. Works great and was a great price. Looking forward to using it on a longer sail. It is cold out there right now

Thanks for your review. I'm glad to hear that the app is working well for you. Fun fact - the app has roots in Niagara as that is where I learned to sail many years ago.
