About this app

See at a glance "when," "where," and "what kind of fish" you can see.
Diving Partner is a new style of diving app that allows you to search for fish sighting information from diving logs across Japan.
You can search logs posted by divers nationwide on a map and narrow down your search by fish name, location, dive site, and time of year.
It's a realistic "marine life map" that answers questions like, "Where should I dive next?" and "Where is that fish appearing now?"

[Main Functions and Features]

■ Map Search Function: A journey to encounter the fish you want to see
The biggest appeal of this app is its function to search diving logs from all over Japan, including overseas, on a map.
You can search by combining fish name, time of year, location, and diving style, such as "When is the best time to see sea slugs in Izu?" or "Where are loggerhead sea turtles appearing in the summer?"
You can also narrow down your search by location, shop name, dive site name, etc., allowing you to access the place you want to go and the fish you want to see in the "shortest distance."
This reliable log search tool can be used directly for planning trips and dives.

■ Posting Function: Log everything you encounter in the ocean—fish, topography, and more!
This posting function allows you to record when, where, and how you encountered fish and memorable scenery in the ocean.
You can enter details such as the fish's name, depth, location, date, shop name, and diving style to preserve the moment of your encounter as a "log."
Your posts can receive "likes" from other users and can be viewed on maps and profiles, meaning your records can be a reference for someone else's diving.
Preserve your encounters in the ocean, and let them lead to connections and future adventures. Of course, like a regular logbook app, you can also record the number of dives, maximum depth, and visibility. Furthermore, you can tag the equipment you used and the people you dived with! Unlike typical apps, it also offers a map summarizing your diving locations, pie charts, and even buddy records showing who you dived with.


■ My Page × SNS Function: Find Opportunities to Connect
You can set tags on your profile to indicate your diving experience, license, style, and frequently dived areas.
If you find common ground, such as "diving in the same area" or "sea slug enthusiasts," you can connect through following or messaging. A log of users you follow is displayed on the home screen, allowing you to quickly check their latest posts.
Casual interactions may even lead to connections that result in diving together.

■ Field Guide Function: Fill Your Own Ocean Field Guide
Photos of fish you post are automatically reflected in the field guide.
The field guide includes a wide range of species from fish, sea slugs, crustaceans, marine mammals, and reptiles from all over Japan. Your completion rate is displayed, so you can see at a glance "how many species you're still missing," adding to the enjoyment of aiming to complete your collection.

It will stimulate your collector's instinct to "complete the field guide with only the creatures you've seen."

■ Diver Type Diagnosis Feature: Diagnose your diver type with a psychological test
Answer seven unique questions to find out which of the 16 diver types you are! Share your results on social media and have fun!

■ Aquarium Feature: Swim freely in a realistic 3D ocean
Purchase realistic 3D models of saltwater fish, coral, seaweed, and more, and place them in your aquarium. Customize your own underwater space.
Switching to landscape mode switches to a first-person perspective, allowing you to swim freely in the aquarium as your avatar. Experience an immersive experience that feels like you're actually diving, even if you've never dived before.
Purchase fish and objects using "coins." Coins can be earned through actions such as posting, liking, and logging in, so you can enjoy the app by building your aquarium even when you're not diving.

【Recommended for people who:】
・Want to plan "where" and "what" to see on their next dive
・Want to meticulously record and share the fish and underwater topography they encounter
・Want to connect casually with other divers
・Love aquariums and want to be soothed by fish
・Are interested in diving but haven't started yet
・Want to experience the real underwater world

An app for divers. But that's not all.

If you love fish. If you love the ocean. Then everyone is welcome.

Install it easily now and start a "life connected to the ocean."

Your posts can inspire someone's adventure.
