### 1/5 — Claims Lake Roosevelt in WA talks about it the Grand Cooley Dam, Spokane. Yet Lake Roosevelt AZ

*2026-07-29*

It claims that it will work for Lake Roosevelt in Washington state to talk about many features of Lake Roosevelt in Washington state you get it and it’s not Lake Roosevelt in Washington state it’s only Lake Roosevelt in Arizona. I don’t care about Arizona. Arizona is on the other side of the country. Talk about misleading.

**Developer response:** Hi Ivy,  no intention to reference Lake Roosevelt in Washington as it’s not yet supported. That is a great lake also. One of the website pages did have incorrect lake references which were overlooked.  Thanks for the feedback!

### 5/5 — Amazing app!

*2026-05-21*

My go to app for boating now!

**Developer response:** Thanks for the feedback!

### 5/5 — Love this app

*2026-05-03*

This app is awesome. So amazing to have easy access to the hazards. Hard to find anything like this.

**Developer response:** Happy it has made a difference for you!

### 5/5 — Very useful app

*2026-01-02*

We’ve taken several family houseboat trips to the lake in years past. We normally relied on maps. I was happy to find an affordable electronic option when I learned of Lake Genius, so downloaded it and subscribed prior to our trip in mid-October 2025.
 
Looking at the app at home I was impressed with the amount of detail concerning elevations and landmarks. In use on the lake, I had a hard time finding a zoom level that would show me both buoy locations and enough elevation / depth information to be useful while underway, but recent updates have fixed that. We found the app very useful overall and a great value.

**Developer response:** Happy the app was helpful Don!  Hope you get a chance to get away to Lake Powell again soon!

### 5/5 — Great app for new & old powell lovers

*2025-09-26*

It doesn’t matter if you’re a newbie or an old Powell lover, this app is brilliant for everyone!! It shows hazards, where beaches are coming out and you can even download offline maps. Plus so much more!! It’s worth every penny!!

**Developer response:** Happy the app improved your experience at Powell. More features and updates coming!

### 5/5 — App will not load

*2025-08-10*

App won’t load it stays on the subscription page even after paying.

Update: Forest ended up taking care of me and got the app working again I had to completely delete it and redownload so that seems it may of been a software issue on my iPhone.

**Developer response:** Hi Greg.  Glad we were able to resolve your unusual situation with a reinstall.

### 2/5 — Has Potential

*2025-08-09*

This app has a lot of potential. I enjoy all of the information this app has to offer; however, the interface is hard to navigate. There are a lot of markers that show hazards and sightseeing locations, but you can’t select them to see what the marker signifies or what the site looks like.

This app has a lot of potential; hopefully, in future updates, they’ll make the interface more user friendly.

**Developer response:** Thanks for your helpful note. Latest updates include the features you requested and more.

### 1/5 — App will not load

*2025-08-01*

App won’t load it stays on the subscription page even after paying. It was a complete waste of money.

Edit: sent support an email and still no response app still does not load

**Developer response:** Hi Greg.  Glad we were able to resolve your unusual situation with a reinstall.

### 1/5 — App will not load

*2025-07-28*

App won’t load it stays on the subscription page even after paying. It was a complete waste of money.

### 5/5 — AWESOME!!

*2025-07-01*

Rarely do I leave reviews on apps, but this is an absolute must have in Lake Powell!! Thank you for an awesome app to help with boating —especially with Lake Powell newbies like us. Heck, even my long time Lake Powell buddies thought this was amazing.

**Developer response:** Thanks for the encouraging words Mxracer317.  Its great to hear the app was beneficial for a safe enjoyable experience.
