Ratings and reviews

Great app! I use it daily to look at the lake levels as my boat sits in the water all the time. I like the new design and features so far. I would like to see the logo that sits in the lower right-hand corner to be moved to the lower left hand corner. This would make the current, trending level better to see. This may change when/if the level goes back up? Otherwise it's great! Thank you for what you've done!

Great app. Use the water level and water temperature features frequently. But what happened to the marina gas prices? That was also extremely helpful!

logo needs to be moved to a different location, with the water so low and dropping you cant see the right side of the current chart. the logo is in the way Thanks.
