Built for the water

A logbook that fills itself.

Explore Riffle the way a day on the water unfolds. Tap a moment.

Plan the trip. Read the conditions. Match the hatch. Pick the rig. Walk to the water already ahead.

Hatchdex and hatch calendar
See what's emerging right now where you fish. Mayflies, caddis, stones, midges, and more. Six insect orders with seasonal windows, and every hatch tells you which fish key on it.
Plan trips and save spots
Pin productive water as you find it. Plan a trip ahead, single day or a whole week. Riffle reminds you the morning it starts, then it turns itself into a live trip and your sessions attach as you fish them.
Conditions read before you go
A multi-day forecast strip that stays with your trip through its last day, plus a plain-language read on what the skies, wind, temperature trend, and moon are likely to do to the fishing. Hedged where the science is thin, confident where it isn't.
Rigs and gear locker
Save your go-to rigs for fly, spin, and surf, and set an active rig per water type. Your gear locker travels with you.

No menus. No typing. Cold-hand and wet-glove friendly. Riffle gets out of the way so you can fish.

Background GPS tracking
Start a session, lock your phone, and fish. Riffle records your exact route in the background all day. Every pool, every run, every wade, mapped without touching your phone.
Two-tap catch logging
Species chip, then checkmark. Done. Designed for cold, wet hands. One-handed, no typing required. Add size, lure, photo, and depth when you want, skip it when you don't.
Live Activity and lock screen widget
During an active session, your lock screen and Dynamic Island show your catch count, distance, and time on the water. Glance, don't unlock.
Works without signal
Built for remote rivers and mountain streams. Riffle saves everything locally and syncs when you're back in range. No cell service, no problem.

End the session and the story writes itself. Route, catches, weather, and milestones, all stitched together.

Session review and replay
See your full route with every catch dropped where it happened, then scrub or play the day back and watch it unfold catch by catch. Missed the start? Place the points you walked before you hit record and the session backfills itself.
Weather at every catch
Pressure, temperature, wind, cloud cover, and humidity charted across the whole session with each catch marked. Finally see what was actually working.
Fishdex across 203 species
Nine groups, 203 species. See what you've caught, what you haven't, and your personal best for each one, with firsts and new bests called out the moment they happen. Your logbook becomes a living record of every species you've ever landed.
Season trends and stats
Watch this season stack up against the last one, month by month. Lifetime, monthly, and day-by-day numbers fall out of the logbook for free.
Photo scan and import
Backfill the days you never logged. Scan your camera roll and Riffle pulls the dates, GPS, and photos to reconstruct old sessions on the water.
Share cards worth posting
Four presets built from your catches, your photos, and your route drawn over real terrain. Swap the hero shot, pick the stats, change the layout, then send it straight to Messages or Instagram Stories.
How it works

Three taps. Then fish.

No setup. No manual entry. No friction between you and the water.

01
Start your session
One tap and Riffle starts recording your GPS route in the background. Lock your screen and go fish. It runs all day without draining your battery.
02
Log catches as they happen
Tap a species chip, hit the checkmark. Done in two taps with one hand. Add size, lure, depth, or a photo if you want, or keep moving.
03
Review at the truck
End the session and see your full route, every catch pinned to where it happened, your stats, and your photos. All in one place. Play it back if you want to relive it.
From the maker

Built by a fisherman.

"I built Riffle because every other fishing app got in the way. I wanted to know which run produced last October, what the pressure was doing when the hatch popped, and which rig I'd had on. Not pay a subscription to log a fish. Riffle is the logbook I wished I'd had for the last ten years on the water."
