Ratings and reviews

Terrific app. My kids and I head out on a fly fishing / truck camping adventure each summer and this app has made finding good water a helluva lot easier. Loads of info to help keep you informed before you head out and the option to download for when you're offline. Great stuff. Thanks!!

This app is a passion project. I asked the developer to try to get data not only for my local river but as well as my local fly shop website and they were able to add them within a few days. I love this app and it keeps getting better and better.

This app is a fantastic resource in and out of the field. I like being able to find all of the necessary data for a fishing or hunting trip all in one place! DriftLine has replaced multiple other apps for my outdoor pursuits.
