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.

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.

This app is very good. I would like more features to subscribe. I would prefer a one-time payment.
