Unique fishing app matching the surface water hatch on all the rivers in Colorado.

Match A Hatch will tell you what fly you're seeing hatching on the river and suggest the correct artificial to use. Simply, tap on one of the riverfly images and the app will do everything else. Touch the fly that looks closest to the one you see on the river, then slide the image over to reveal the correct artificial and information about the fly. Manipulate the image with your fingers to get maximum close ups of the stunning images taken from the live flies.

That's it. You are now fishing with a lifetime's worth of knowledge, letting you deepen your knowledge and enjoyment of fly fishing.

Match A Hatch will enable you to:
+ identify any fly you see on the river
+ correctly pair that fly with an artificial
+ learn the names of the flies both Latin and in English
+ learn the characteristics of the fly
+ see astonishing hi-res images of the flies.

Great Idea and helpful to fly fishers everywhere

This is a free app that allows you to translate what you are seeing on the river into flies that might be suitable. While not exhaustive there are plenty of options and some tips along the way.

Misses the point

It doesn’t tell you what you’re seeing on the river you select from a list from the month and it shows you some options. It ignores all sub surface insects and doesn’t have enough pictures to really help. Great idea but doesn’t meet the needs of this angler
