Update to prior review: Baseline continues to improve. It’s amazing what this app delivers all in one place. Gone are the days of checking multiple government websites to get water data to add to my catch journal. The integrated feature in Baseline captures all the relevant water and weather data when you record a catch. Wondering about run timing? The app now has integrated catch statistics from state wildlife agencies. Literally any data you want, it’s in there. The developers commitment to continual improvement of this app is second to none. They are responsive and quick to add requested features. I’m blown away by how much they continue to improve. It takes a truly special person to take a fantastic app and keep growing it into something uniquely outstanding. I cannot recommend this app highly enough. DriftLine has been a game changer for me. Having all the data for all the rivers I fish in one place is so convenient. Also, the integrated journal feature is incredibly helpful in identifying trends for what presentations work in what conditions. If you want to take your fishing to the next level, get this app.

CH4, reviews like this keep me going and I couldn't be more grateful to continue building Baseline Maps with folks like you that run it hard. If you ever need anything or something within Baseline needs improvement, we'll do our best to make it happen within the week. Have an awesome 4th!
The App above all outdoor apps
TNFarr
I honestly love using the Baseline app!! It’s been a total game changer! Before this, I was constantly bouncing between multiple apps trying to piece together the info I needed, which was frustrating and time consuming. Now, everything is in one place, and it just makes sense.The features are incredibly helpful and actually feel built for real people who spend time outdoors. And just when I think it can’t get any better, the founder releases even more mind blowing features I didn’t know I needed. It’s simple to navigate, super reliable, and runs smoothly every time I use it, which is huge when you’re out in the field and don’t want to deal with glitches.If you’re into hunting or fishing, I can’t recommend Baseline enough. It’s one of those apps you didn’t realize you needed until you have it and now I couldn’t imagine a life without it!

Makes learning easy
Kimberly J Harris
This app deserves 5 stars in every aspect. I’ll be the one to say as a female in the fishing world, Driftline has made getting out on the water so much less intimidating. I love that it gives me an idea of what to pay attention to. The app is clean, easy to understand, and doesn’t feel like it’s only built for hardcore anglers, and with no judgement either. It’s nice to see something that feels welcoming to women who enjoy fishing too, whether you’re just starting out or have been fishing for years. It’s become the number one app for women and men and kids all around. The turn around on the suggestions is amazing as well. This feels like a huge break from the invasive and hard to navigate apps.
Developer Response
Thank you so much for the incredible review! This is what keeps me going is knowing that the community and folks like yourself who are out on the water putting it through its paces - enjoy it. If you ever need anything such as a new feature or find something with Baseline that needs attention, please don't hesitate to reach out!
Best outdoorsman app out there
Eric B Miller
I just want to say thank you to DriftLine for allowing me to be part of their project. From being able to be one of the first founders members. If it wasn’t for a friend of mine recommending the app to me, I would have never known about it or gotten the chance to be part of it. I have watched it grow into something I find so valuable. I can’t wait to be able to get out in the field and use it more. There is so much more it offers compared to other outdoor apps. Thanks again for all you do and have done for us. I appreciate it so much. Eric Miller
