Wi-Fi Checker

This app notifies you in three ways when you disconnect from or connect to WiFi.
1. Notification by color (select from 9 colors) (screen background color)
2. alert notification
3. Audio notification (select notification or non-notification)

Furthermore, the record of when you connected to and disconnected from WiFi (date and time, WiFi connection destination) for the past 60 days is saved, so you can check it later.

This app is used in conjunction with the Shortcuts app (standard on iOS), so initial settings are required.
The initial settings are explained in detail within the app, so even beginners can set them up.
