Ratings and Reviews
Alerts!
This app not only has a sleek, user friendly design, it also has alerts for changing conditions and widgets to add to your Home Screen. Save your regular fishing spots to your favorites and enable alerts for the best experience. Worth every penny!
Room for improvement
The apps appearance and interface is great. I like the ability to see temps in conjunction with the flow.
Why I give it a low rating is that I’ve found the graphs are only graphing readings one or so times a day, and often lagging several days.
Unfortunately I’ve already paid for a year subscription so I have invested hope of seeing improvements within the data representation and frequency.
Developer Response ,
Thank you for the review and also thank you for being a subscriber. If you are not completely happy with the subscription then please reach out to Apple for a refund. They have a liberal refund policy and I’m confident they can help.
Regarding how often the data is updated: yes charts are only showing the average value for a particular day. It doesn’t show data any more granular than that. Second, if the chart isn’t updating for a few days, then that’s because the USGS data isn’t updating in that time frame.
That being said, the latest version (3.0.0) does incorporate NOAA data for charts and for some streams that means that there is more data available. Unfortunately there is a wide spectrum of data and how often it is reported from stream to stream.
Finally, in the latest version I have an option for a free 7 day trial. Hopefully that helps users get the advanced features and try them out before they pay.
Thanks again. And if you find that any of this helps then please consider updating your app rating as that really helps me out.
Fire app
It’s so helpful to see river flow info before you hit the trail and this is the best app that I’ve found. There’s complex data presented in a simple way. Widgets are immensely helpful for conditions at a glance. Invest in the premium version to conquer fish like never before.
