Edit: Too expensive for listing out CFS, water temperature and weather. They dropped favorites from 6 to 5. I'm not paying $36 when I can get Trout Routes for $16 more. What I like: I really like the layout and ui of the favorites. It's easy to see and you can see the flows and the weather at each spot with a simple 3 day, 7 day or 30 day flows. It has replaced my previous app for planning my fly fishing and canoe trips.

Hey Marc, thanks for the feedback. We hear you on pricing. A $19.99 yearly subscription will be coming soon, which should be a much better value. Glad to hear you’re enjoying the favorites layout and flow views.

Decent app but not as user friendly as others. It won't let you delete it or remove your info from it, so make sure you really want to download it before you do. Every time I try the delete account option in the app it fails and tells me I need to contact customer support. Not worth your time if it's this hard to delete. The free app will only let you save 5 favorite river gauges.

Thanks for the feedback! I'm sorry to hear that the “Delete Account” option isn't working for you. I'm looking into it now. If there’s anything that felt less user-friendly, I’d love to hear more so I can keep improving the app.

Even though I paid for the subscription it still won't let me look at my favorites!
