If you're an angler, you know that keeping a detailed journal of your time on the water is one of the best ways to up your catch rate. That's because, over time, your journal will show you patterns in when and where fish bite, and what lures and baits work best under different conditions. The more detailed your journal is, the more of these patterns you'll see. But keeping a detailed journal requires time and dedication that most anglers can't afford.
Not anymore. Field & Stream's FREE new Catchbook app, just released on the iPhone, is designed to take all the work out of keeping a fishing journal. The app does this by taking photos of fish you've already shot with your phone and automatically converting them into detailed fishing reports that include the weather and water conditions present when those photos were taken. The app pins each report to a map, then lets you share them exclusively with trusted friends and fishing buddies. The more friends you have, the more reports you see on your map, and the easier it becomes to pattern your spots!
Our editorial team has been working for nearly half a year on the project, and it finally launched last week. Now we're looking for feedback from the people we designed it for. You! If there are bugs, we want to know about them. If there's something you think we can improve, we want to know what that is. And if you love something we've done? We want to know that, too.

We'll incorporate your comments into updates to the app, which we're planning to roll out regularly. You can give us your feedback by commenting on this post, or within a new "Catchbook" category in our online Answers section. And, right now, exclusively for readers of this site (and for a limited time only) if you sign up and request user "Field & Stream" as a friend within the app, we'll add 5,000 points to your F&S Online username.
