### 5/5 — New update issue

*2025-06-16*

App is super useful. Unfortunately, it stopped updating waves and wind on Friday 13 June. I deleted and redownloaded, but experience was same.

### 3/5 — App doesn’t update date

*2022-06-29*

Not sure what happened but my app worked fine for years. Recently it updated when opened but doesn’t update when scrolling to different times.

**Developer response:** Hi!

Thanks for the report! Unfortunately, I’m not able to reproduce this issue. It appears to be working as expected on my end. Perhaps delete the app and download it again from the App Store? Feel free to reach out to me on Twitter to investigate this further. 

Thanks!

Jeff

I am hard core fisherman, It was hard to look at  the phone when comes to the Great Lakes conditions specially wave heights, I was so dependent on the laptop, since I got this app it made the life easy!

### 5/5 — Excellent for checking waves

*2019-12-28, version 3.1*

We have a cottage on Lake Huron. I always check the wave conditions before going up and while there. The app is extremely accurate.
