## What is Aisea?

◦ Radar mode
Aisea App's Radar mode displays the movement of vessels in the vicinity equipped with AIS or using the App on a scalable chart. When it detects a risk of collision, the App will warn you minutes ahead. Aisea brings you peace of mind on the sea.

◦ Map editor and reporting tool
Users can report dangerous floating objects from Aisea App, and Map Editors with business accounts can set various areas that require the nearby sailors' attention. Those reported markers may be public and visible on the chart for others or private and hidden.

◦ Voyage playback
Playback the past voyages on the web anytime with videos and other voyage data since Aisea automatically saves them as your vessels navigate. These playbacks help investigate in case of accidents and are useful for optimizing navigation courses.

◦ Fleet management
The Fleet Management interface is available for affordable Business accounts, letting you keep tabs on your fleet, clues, operators, and anyone you need to communicate for your everyday tasks. You and your operators can access the interface from your PC, smart device from anywhere anytime.

◦ Vessel tracking
Aisea monitors vessel locations through Aisea App and AIS stations on the shore and ships. Vessels will be appropriately represented by vessel-shaped icons in scale rather than dots or triangles so that you can grasp the situation intuitively.

◦ In App Push-To-Talk
Communicate with nearby users without radio equipment. UX is carefully designed to resemble the Marine VHF radio with plenty of guidance, so the learning curve will be shallow for everyone. Business users can talk within their business or projects.

### 1/5 — 何でこんなに評価良いのですか？エラーばかりで使い物になりません。

*2026-06-11, version 2.4.0*

使用端末は通信環境良好。船舶追跡で使用。該当の名前検索をしてもヒットした名前が小文字大文字の違いなのか押しても表示されるものとエラーが出るものとある。
昨夜まで追跡していて、今も航行中の船舶が表示されなくなった。他社アプリだと表示されるので切り替えます。改善した方が良いのでは？

### 1/5 — 表示について

*2022-07-27, version 2.3.0*

全体的に幼稚な表示されているので、改良の余地があるのではと思います。

### 3/5 — まっさきに‼︎

*2021-12-09, version 2.1.1*

大阪湾から明石沖を見れるように頑張って下さいよ‼️

### 1/5 — 最低限日本列島はカバーして欲しい

*2020-12-10, version 2.1.1*

このままでは使い物になりません。
日本はグルリと海に囲まれた島国ですよ？

### 5/5 — 凄くいいです。関門海峡を航行時に活用

*2020-06-30, version 1.1.13*

AISもタイムリーに出て、非搭載船での航行時にはわかりやすく、愛用してます。また、無線機能と仲間でのクルージング時に活躍❗️
Wi-FiでのiPadでも活用出来たらいいなぁ…

### 3/5 — 福岡 東京 北海道(釧路) のみ表示

*2019-08-13, version 1.1.0*

福岡 東京 北海道(釧路)のみ表示されます
他のエリアは船舶表示されません
これからの対応に期待します。
