The Fly Fishing App That Tracks Your Catches, Weather & Adventures
Cast Companion is the fly fishing journal and weather tool built for anglers who want to log every catch, plan trips around river conditions, and connect with fellow fly fishers across the UK.
Why Anglers Choose Cast Companion
Log Every Catch. Build Your Fly Fishing Journal.
Keep a detailed record of every fish you land — species, fly pattern, river conditions, and more. Cast Companion turns your catches into a searchable fly fishing diary that helps you spot patterns, refine your technique, and relive your best days on the water. Whether it's a wild brown trout on a dry fly or a hard-won salmon on the Spey, every catch tells a story.
River Weather Forecasts Built for Fly Fishing
Standard weather apps don't cut it for anglers. Cast Companion gives you river-specific forecasts with the details that matter — wind direction, barometric pressure, rainfall, and temperature trends. Plan your trips around the conditions that produce the best hatches and the most active fish. From spate rivers in Scotland to chalk streams in the south, get weather data that's actually useful on the bank.
Connect With Fellow Fly Fishers
Fly fishing is better shared. See what your friends are catching, discover new rivers and techniques, and be part of a growing community of passionate anglers. Cast Companion's social feed lets you share your catches, follow fellow fly fishers, and stay inspired throughout the season. No noise, no ads — just real anglers sharing real fishing.
