In the "Know" category, you can find news and weather updates for the region. The app sends push notifications for significant news and weather alerts. You can also check disaster information, traffic updates, and the latest YBS events.

Under the "Watch & Listen" category, you can access exclusive videos and official YouTube channels. You can also find YBS TV and radio show schedules and program information.

The "Send & Apply" category allows you to submit photos and videos to YBS投稿BOX, send messages to radio shows, and apply for TV and radio show giveaways.

Lastly, the "Enjoy" category offers coupons for popular shops in Yamanshi. You can also register your star sign and receive weekly horoscopes and accumulate points for participating in the app's daily lottery.

Overall, the YBSアプリ aims to be a comprehensive platform for all things Yamanshi, providing residents with all the information they need in one place.
