AI measures your catch's length, girth and estimated weight, identifies the species, and creates a private digital journal — all in seconds. Proof, Not Guesswork No board, no tape, no guessing. A Proof Ball or Proof Bar in frame is all the app needs. Snap a photo or record a video and the numbers are waiting when you're done. Reduce Fish Handling Measure it. Release it. Faster. Less time out of the water means a healthier fish and a healthier fishery — a practical addition to any angler's gear, from bass boats to fly rods. The Most Accurate Way to Digitally Measure Fish Proof products give the AI a known dimension to measure against, so length and girth are verified measurements, not estimates. Weight is calculated from length and girth and always labeled as an estimate. Used correctly, nothing on your phone measures a fish more accurately. Support Conservation Every catch can count for science — only if you say so. Choose to share your catch data anonymously, without precise location, with vetted fisheries science organizations like NOAA to help protect the waters you fish. Never automatic, and you can withdraw at any time. Digital Journal & Automatic Species ID AI identifies your fish and logs species, size, location, time and weather to a private digital journal and map of your catches. No manual data entry. All your catch data in one place. Online Contests & Challenges Create or join fishing tournaments using your real catches. Compete privately with friends or publicly with anglers around the world. Catches can be scored as a percent of their world record, so you can compete fairly even when you're catching different species. Real catches. Digital leaderboards. For Your Whole Trip Fishtechy’s Story Mode tracks your entire trip, including miles walked or floated, a map of your route, elevation gained, and fish caught along the way. Track the whole trip with the Fishtechy app Your Data, Your Call Your catch data stays under your control. Nothing is shared with scientists or anyone else without your explicit consent. The proof is in the ball. Download the free Fishtechy app today.

RiverGhillie is the complete digital journal for salmon and trout anglers on Scottish rivers. Track every catch with GPS precision, monitor live river conditions from SEPA, and get the weather data you need to plan the perfect trip — all in one beautifully designed app. KEY FEATURES • Catch Journal Log every fish with species, weight, length, location, photo, and release status. GPS coordinates are captured automatically from your photos. Each catch is enriched with live SEPA river level data from the nearest monitoring station, so you'll always know what the water was doing when you hooked that fish. Log hours fished and the no-touch days too — blanks are half the pattern. • Ghillie's Advice The ghillie reads today's live level, trend, rainfall, weather and moon phase to recommend a line, tip, fly size and three flies — grounded in your own catch history and the classic patterns of your river, with a warning when today's water looks like water you've blanked on before. • Interactive Catch Map See your entire season laid out on a map at the bottom of your journal. Every catch position is plotted, and you can tap any catch to fly straight to its location. Each catch card has a map icon — tap it to open a full-screen map where you can view, adjust, or drop a pin to set the exact location. No GPS from your photo? No problem — just drop a pin manually. • Live River Levels Real-time data from SEPA's network of ~775 monitoring stations across Scotland. Search any river, see current water heights, track trends (rising, falling, or steady), and view interactive charts spanning 1-day, 3-day, and 7-day windows. Set alerts to get notified when water levels rise on your favourite rivers. • River Flow Data Monitor discharge rates (m³/s) alongside water levels, with short-term (6h) and long-term (24h) trend indicators so you can time your trip perfectly. • Weather Forecast Detailed hourly and 7-day weather forecasts powered by Open-Meteo. Wind speed and direction, temperature, rainfall, humidity, pressure, and cloud cover — presented in a clear, XCWeather-style format. Add weather favourites for the locations you fish most. • Rain Radar Play back the last two hours of observed rain plus half an hour of forecast over your location or any river. • Weather History One tap backfills the actual air temperature, wind, conditions and 24-hour rainfall at each of your GPS-pinned catches. Every catch also shows the moon phase for its night. • Tide Stations Tide predictions near river mouths, offset for how long the tide takes to reach your river, with one-tap directions via Apple Maps. • River Detail Pages Dedicated pages for each river showing all monitoring stations, interactive level and flow charts, tide stations near the river mouth, weather conditions, and beats and pools contributed by the community. • Community Beats Map A shared, crowd-sourced map of beats and pools. Any angler can add a beat with coordinates and notes — instantly visible to all users. One-tap driving directions via Apple Maps or Google Maps. • Crew & Social Connect with fishing friends. Send and accept friend requests, see your crew's recent catches, and share your angling journey. • Catch Insights Visualise your season with detailed statistics — species breakdowns, catch trends, weight distributions, fish per hour, blank sessions, and SEPA level correlations. Spot patterns and improve your strategy. • Notifications Get alerted when river levels rise on your favourite waters, when friends log new catches, and when you have pending crew requests. Custom sonar ping notification sound. • Cloud Sync & Privacy Your catch log syncs securely to the cloud via Supabase, so your data is safe and accessible across devices. Favourites, weather locations and pinned stations sync too. Apple Sign In for secure, private authentication. RiverGhillie is built by anglers, for anglers. No ads, no clutter — just the tools you need to make the most of every trip to the river.
