Beyond just providing internet access, the app can display localized information relevant to the Wi-Fi service coverage area. This may include sightseeing details, information about shop services, and disaster-related updates.
The app supports a wide range of public Wi-Fi services available across Japan, including those found in public transit, stations, airports, convenience stores, and department stores. It also automatically connects to Wi-Fi that supports OpenRoaming.
