About this app

Diving begins with choosing the right ocean.

"Where should I dive next?"—the moment you think this, your diving adventure begins. DiveNote is an app that helps you find your next dive destination based on ocean conditions, marine life, and divers' records.

It not only records dive logs, but also brings together ocean condition information for nearly 200 spots nationwide, a comprehensive marine life guide, and the ability to share records with fellow divers. From choosing your next dive to reflecting on it afterward, DiveNote is there to support you.

■ Finding Spots with Ocean Conditions and Marine Life Information
You can check ocean condition data (visibility, water temperature, etc.) and the types of marine life commonly found at a particular spot on a map. Knowing "what can be seen at this spot right now" allows you to plan your next dive.

■ Discover Unique Marine Life
Discover unique marine life specific to each spot through divers' log data. This provides hints when you're unsure where to go next.

■ Don't Miss Seasonal Creatures
The app automatically compiles information on the types of creatures most likely to be encountered at each spot during that month and time of year. It tells you about encounters you can only see by diving now.

■ Extensive Creature Encyclopedia
Equipped with a creature encyclopedia with rarity levels from E to S. Your achievement rate is visualized based on your records, allowing you to enjoy diving with a collection-like feel, aiming to encounter rare creatures. If you mark the creatures you want to see, you'll be notified when they are actually discovered or posted somewhere.

■ Easy Log Recording
Numerical items such as water temperature, visibility, and depth can be intuitively entered using sliders. Entry and exit times can also be easily recorded with wheel selection, and the stay time is automatically calculated (manual overwriting is also possible). Your records can be a hint for someone else choosing a dive site next.

■ Sharing Records with Friends
Follow your diving friends and check each other's public logs. You can also record memories with your buddy using the messaging function via QR code (Buddy Sign).

■ Review on My Page
View a list of diving statistics, including total dives, number of visited spots, and number of species seen. Your accumulated experience is visualized.

■ Designed with Privacy in Mind
You can choose the visibility of your logs. Even logs set to private are used as anonymized statistical information to improve spot sea conditions and marine life data.

【Recommended for those who:】
・Want information on sea conditions and marine life to help them decide on a destination
・Want to keep a record of their dives and look back on them later
・Want to be motivated by encounters with rare marine life
・Want to casually share diving records with diving friends
