About this app

"Why did I catch so many fish that night?" The answer lies in the conditions. Ajito records your catch from a single photo, automatically linking it to the tide, moon phase, weather, wind, and water temperature at that time. The more data you accumulate, the more your unique winning patterns and optimal fishing times will become apparent.

■ Easy Recording - Just Take a Photo
- AI automatically determines the size and type of horse mackerel (Japanese horse mackerel/round scad/big scad) from the photo
- Location and date of catch are automatically entered from the photo information
- Record ajing-specific items such as range, worm color, rig, and tide with just a few taps
- Reusing the same photo is blocked to protect data reliability

■ Tonight's Big Catch Index and Optimal Fishing Time Prediction
- Compares past catches with the day's sea conditions (weather, wind, water temperature, tide level, tidal cycle) to display a big catch index score
- Determines rising and falling tides from Japan Meteorological Agency tide level data. Displaying the "30% rising tide, 70% falling tide" timing on the tide graph
- Recalculate the forecast for your destination on the spot simply by moving the map
- Receive "Big Catch Alert" notifications only on days with good fishing weather (up to twice a week; not daily)

■ Visualizing Winning Patterns
- Automatically tally the tide cycle, time of day, range, color, and rig where you caught fish
- Understand your own patterns numerically, such as "Medium tide, rising tide, 7-9pm, count 5, clear lure"

■ Heatmap of Everyone's Catch Rate
- Display the catch results of ajing anglers nationwide on a heatmap in approximately 5km area units
- Specific point coordinates and location names are not shared, protecting your valuable locations

■ Designed with Privacy as the Top Priority
- Latitude and longitude of fishing spots are not displayed on the screen and are never disclosed to other users
- Only anonymized statistical information is shared

■ For those who:
- Want to properly record their ajing (horse mackerel fishing) catches
