Very good

Nice and useful, but could be more helpful to people who are not advanced fly anglers.

I would find it particularly useful if it described the various kinds of fishing (swinging, stripping, etc.) that one is asked to select, and perhaps even describe what situation and/or species each method is better for. Or it could ask me what species I intend to fish for the most, in what setting, and take it from there.

It also could have a wider selection of fly rod brands and especially models that one can select, including older ones.

Finally, sometimes the suggested fly lines are questionable; for example, I looked for a fly line for a fly rod model that is 13’9” long; however, it recommended a fly line meant for shorter rods. It’s hard to know whether that is a mistake or not.

This review is not meant to discourage users from installing the app, but to encourage RIO to make it more user friendly.

Good Start!

I like the app, but suggest you allow for more models of the various manufacturers. The largest part of the market that would use this app may not have purchased a rod this year! If I purchased a new Sage 3 yrs ago it's not in your app for example.

You would attract even more interest in the app (and your product) if you overlayed even rods made 10 yrs ago against the best current line setup for it...

Needs to be updated for newer versions of IOS

Don’t try to download the app until the re-release it or remove it from the App Store. It will not run on IOS 14.6 and you will be stuck with the endless “app needs to be updated” message until you can get delete from your app list.
