REQUIRES iOS 4.2 OR GREATER. Field & Stream’s Catchbook is a map-based social fishing journal that makes it extremely easy for you and your buddies to pattern the places you fish. Use it to learn where fish bite (and what flies, lures, or baits work best) under different weather conditions and at different times of the year. All without ever sharing your spots with people you don’t trust. Here’s how it works.

POST YOUR PHOTOS
Catchbook lets you turn any fish photo you’ve ever taken with your iPhone into a detailed journal entry that includes the time, date, location, and weather present when you caught each fish. Upload any fish photos already in your camera roll to get started, then make sure to snap away the next time you’re out on the water. Add records to your journal by choosing the photos you want to upload and telling us the species of fish in each photo. The app does the rest! Add optional information (such as the size and color lure you were using) to create even more detailed records to share with your friends.

FIND FRIENDS TO POOL YOUR RECORDS
The more friends you invite into Catchbook, the more catches you’ll see on your map. And the more catches you see, the easier it will be for you to pattern your spots. Inviting friends is easy. Invite people you’re already friends with on Facebook, or send your fishing buddies invites by email. You can also find new people to fish with by searching for other Catchbook users who fish in the same places you do.

PATTERN YOUR SPOTS
Every time you (or one of your friends) posts a photo to Catchbook, that photo gets pinned to a spot on your map. Filter your map to show only fish caught at specific times of the year, at different times of the day, under specific weather conditions and water temps, and much, much more! You’ll quickly see patterns in which spots work best under different conditions. Then use the app’s “Best Baits” features to learn which flies, lures, and baits (and their colors and sizes) caught the most fish under the conditions and areas you’ve selected.

Map filtering options include:
-- Fish species and fish size
-- Time of year and time of day
-- Moon phase
-- Wind speed and direction
-- Water temperature, water clarity, lake/river level, and tidal stage
-- Barometric pressure and barometric trend
-- Air temperature, cloud cover, and precipitation type

WATCH CATCHES IN REAL TIME
Keep an eye on what people are catching around the country by clicking on the “Catches” tab. You’ll see all the latest fish entered into Catchbook (photos only — no spot burning here). You can filter the photos you see by both fish species AND specific location (by zooming in on a map) to keep tabs on the action in your favorite spots!
