From the developer:
Charged? is a small application that allows you to check the charge level of your iOS and macOS devices via Bluetooth and iCloud. Your devices sync their battery status locally via Bluetooth and if you have an iCloud account, they will sync via an Internet connection as well. You can easily hide devices you don’t care about or unhide them at a later date.
