TsuriDEX - 等深線と海底地形の釣りマップ

Find the best fishing spots at a glance.
"TsuriDEX" is a next-generation map app for anglers that evaluates and visualizes fish hiding spots with a ranking system from S to C, based on water depth and terrain changes.

From scouting fishing spots in advance to AI-powered size measurement from photos and catch analysis, it powerfully supports your fishing life, from beginners to veterans.

[Its greatest strength: A high-performance map that shows the best fishing spots]
This is not just a map. In addition to seabed "water depth" and "contour lines," the AI ​​analyzes bottom quality data such as sudden depth changes (breaks and drop-offs). Promising areas where fish are likely to be found are directly displayed on the map with S, A, B, and C rankings. If downloaded in advance, it can be used as a GPS offline map even in offshore reefs or mountain streams without cell service.*

[Other key features]

■ AI automatically identifies and measures fish
Simply take a picture of your caught fish with your smartphone. The latest AI instantly identifies the "name of the fish" and accurately estimates its "size (length and weight)." You can record your catch digitally, like a digital fish print, without the hassle of using a measuring tape.

■ "Sea Conditions Forecast" Directly Impacting Your Catch
In addition to weather forecasts, you can check wind direction and speed, wave height, and detailed tide graphs (tide tables) up to 7 days in advance, allowing you to plan your optimal fishing trip. *

■ Your Personalized "Fishing Analysis Dashboard"
Based on recorded data, it visualizes your "winning patterns." The AI ​​automatically calculates the successful conditions for tidal cycles, wind direction, and water temperature that you often use. *

■ Fishing Tackle Inventory
Register and manage your favorite rods, reels, lines, etc. Link it to your fishing diary to record in detail which tackle you used to catch fish.
